Wavebox | Chat Unification Snap Application on openSUSE Tumbleweed

Wavebox on openSUSE

From time to time, I like to play around with the universal packaging available in Linux. It has mostly been AppImages and Flatpak but I wanted to Snap something into my system. After working out an AppArmor issue. Snaps were working fantastically well once again. The application I wanted to try was another Chat Message Unification Application. I had heard wonderful things about Wavebox so it was time to try it out. It’s described as, “A clever new home for cloud apps on your desktop bringing Gmail, Inbox, Outlook, O365, Trello, Slack & over 1000 more apps into a configurable client.”

You can look at the details here on the SnapCraft store.

Wavebox Snap 19

In a terminal I installed Wavebox from the Snap Store:

sudo snap install wavebox

Installation was a snap (haha) and it created an entry in the application menu of KDE Plasma, just as one would expect. It should also be noted that the system tray icon also looks great next to the rest of the icons sitting there too.

When the Application started up, I didn’t notice any lengthy start up time that has been complained about in the past with Snaps. It was delightfully… snappy… and when it settled I was greeted with a pleasant interface. There was no question as to what I needed to do, create an account.Wavebox Snap 2

Going through the process was really quite trivial. You begin by entering your name, email and password. I elected to setup two-factor authentication which did require me to install an application on my phone…

After you have logged in, you can add your first application. I went with Slack, specifically the Bad Voltage slack group. There is a convenient search box right at the top of the uncluttered interface.

I am not 100% sure what the “Pic a Colour” section does, entirely but it does create a ring around thee account on the side tab of the service. Setting up Slack was trivial and has the same basic feel of what you would have in the web browser.

What I think is interesting is the different customization features you can specify for each module you add. What is interesting to me is the ability to put a tab to sleep and stop it after some time of inactivity. I don’t know exactly what that means and how it is implemented but if that is what I am thinking it is, that should be more kind to your system when on battery power. I find with all the services running in either a browser or other Chat Unification applications, the CPU usage is noticeable.

Wavebox Snap 11

I wanted to install the G-suite of tools and began that process by selecting the Gmail icon when adding an application. There is a similar “Pick a Colour” selection then you can choose which services it loads into this “tab”. I didn’t test all the functions but the ones that did worked as expected. The Hangouts button doesn’t give me the hangouts configuration I prefer but it is functional, none the less.

Wavebox Snap 13

Setting up the account is much like logging in through a browser or even Kmail, for that matter. When you sign in, you then configure the default inbox configuration.

The display of the email is as you would see in a web page but the added benefit is that you have all the other services on a menu bar at the top of the Window. This is, by far, the best implementation of interfacing with the Google Services I have ever seen. It is far more functional than the Google defaults and even nicer than what I have been using on similar services.

Memory Use

It’s very easy to see how much of your drive is taken up by the application

/dev/loop11 156M 156M 0 100% /snap/wavebox/180

I don’t view this as outrageous at all. The application has another 181 MiB of storage on my home directory in the snap folder. I haven’t fully investigated the the contents of the folder but it does keep historical snap version configuration files, which is interesting.

Running the 10 Google Services, Riot and Slack, I am using about 490 MiB of RAM, so, 12 services in all on this so about 40.8 MiB per service. Combine that with the sleep function, this doesn’t feel too bad.

What I like

The way that Wavebox bundles the Google Services into one tab and how integrated and purposeful it feels makes this application really quite special. There is a lot of thought and detail put into it. I would say that this is a far better “Google Experience” than what you would have on a Chromebook. It is, seemingly a much more efficient and integrated experience, really, the best I have ever seen.

The Sleep Tab feature is very interesting and I have not studied it enough to know exactly how it works because I have received email notifications while the tab was sleeping so it must check periodically. somehow. I would really like to run this on a long term basis and determine, or at least, better determine what it is doing. Maybe even do some CPU usage comparisons between Wavebox and similar services but I just don’t have the time for that.

The conveniences of having all the different communication and collaboration services in one window, everything unified, is very conducive to productivity. That feature alone makes this application stand out from others similar to it. I would determine that it is a better experience than what you have in a browser with a string of pinned tabs.

What I Don’t Like

Wavebox does requires a login to an external server someplace to manage your accounts. This is like the Franz application I have also reviewed. It was an area for which I didn’t particularly like. I do see the utility of it and since these are all services you are logging into, one more isn’t that big of a deal… really… but somehow that is still a sticking point for me.

Wavebox isn’t free. Not that I think everything should be free but I would rather spit out a one time payment for this application. It costs $48 per year to use this application. For my purposes, since my efficiency with any of these services is not a part of my job, (arguably maybe Google could be), it isn’t a good value for me to make the investment. However, if your work required you to communicate on numerous  services regularly, I could absolutely see this as being a vital piece for improved quality of [computing] life.

Final Thoughts

Wavebox LogoRambox and Franz are both similar applications I have reviewed, albeit with a slightly different lens, they are all really quite fantastic applications. Any one is a good choice and I am glad that they all exist. There are features from each application that I appreciate so each application has their merit. I would say that of all of them Wavebox does seem to have just a bit more polish than the rest. There are more tools and tweaks with this and the way all the Google Services are rolled up with a very convenient menu makes this the best experience for using G-Suite. Far better than even with Chrome or using a Chromebook. This is so nicely integrated that it makes a mediocre web application experience feel like a real, nicely polished, and purposeful, native application.

Wavebox is, undoubtedly, suited for the professional user, not so much a dude like me that can’t seem to stick with an application like this for more than 6 months or so. This is extremely well thought out and well executed. Features like the Sleep Tab make this stand above other options.

Another final thought, having access to Snaps (along with other universal packages) available on openSUSE Tumbleweed really opens up a very wide array of available applications for my use. Snaps seem to integrate well into openSUSE; just as long as nothing gets messed up with AppArmor again. Snaps are a great choice for application delivery for many cases and I am thankful that I have access to them.

Outside the Cubicle | Sledgehammer Repair, Handle Replacement

Sledgehammer Repair.png

Last fall (2018) I broke my “new” sledge hammer. I had maybe gotten all of 3 months of use out of it and snapped the wooden handle right below the business end. After much consternation, I picked up a fiberglass handle instead of a wooden one mostly due to the feel and finish of the handle.

I started out by removing the remnants of the old handle out of the the sledge as to get it ready for the new handle. This was a more aggravating process than anticipated. Lots of drilling, chiseling and hammering to free the steel from the splintered wood.

Outside of working and playing in Linux, I have always enjoyed working with my hands on projects. Sometimes, my fingers need a break from the keyboard and I need to break or fix something.

This is my folly and success in fixing a sledge hammer. The installation of the handle was academically not a complicated process but the execution did have its challenges.

I am trying to learn Kdenlive in hopes that I can become effective with the software. This is a cobbling together, learning to edit video through the various features. It’s been enjoyable and this is my cobbled together result.

SimpleScreenRecorder on openSUSE

A fine tool for which I recently had some use is this very capable application called SimpleScreenRecorder. I used it to create a couple simple videos mostly to see how well it works but mostly for the purpose of creating something useful as a reference.

To install it on openSUSE use the one-click method here:

https://software.opensuse.org/package/simplescreenrecorder

Or, my preferred method, in the terminal, enter:

sudo zypper in simplescreenrecorder

Fantastically, it is built using the Qt toolkit so it looks much better in the KDE Plasma Desktop Environment.

I have used it for a couple videos and have plans for more, mostly as notes to myself but in video form.

Basic Usage

After installing the software, it will sit in the multimedia subsection on the menu. It can be called up in a search as well, at least on Plasma.

SimpleScreenRecorder 1

Select Continue

Next you are presented with your Input Settings. You can create different profiles for different purposes. You can also select if you want to record all the screens, a single screen, a fixed rectaning, follow the cursor or to record OpenGL. I have only used the options to record the entire single screen or a fixed rectangle.

SimpleScreenRecorder 2

You can choose to record the cursor or not and whether or not you want Audio. I have only used PulseAudio and it has seemingly worked just fine.

When you Continue, you will have to select the Output Profile or create your own, set the file name, the video and audio codecs settings. The settings pictured below has worked quite well for me in terms of quality but are a bit excessive in the memory usage.

 

SimpleScreenRecorder 3

After all that is set, you can start recording at anytime. It is also not a bad idea to Start the preview if you want to make sure it looks right before beginning the recording. The information frame on the left side of the window is quite nice. It tells you all kinds of useful information about the process. What is especially good to know is the file size. Depending on your available system resources, this could become somewhat of a concern.

SimpleScreenRecorder 4

Once you have completed the recording, hit Stop Recording along the top of the window and Save Recording if you believe you are satisfied with the results.

And that is it!

How I’ve Used It

I wanted to demonstrate how to set up switching from left-to-right typing to right-to-left typing on LibreOffice

I also did a quick little video just to play with SimpleScreenRecorder and showing how to turn on and off tooltips within KDE Plasma 5.16. I did edit both of these videos with Kdenlive for practice because someday, someday, I might get good at it.

Final Thoughts

SimpleScreenRecorder is a fantastic example of easy to use software to create simple videos for any number of things. This is great for demonstrating how you accomplish something on the desktop, sometimes video is the best way to present it. This is a fine example of easy to use open source and free software that has an incredible value.

Since I am able to install this application from the official repository with my favorite Linux distribution openSUSE Tumbleweed, it is just another straw on my pile of reasons I use it. Additionally, it requires no fancy configuration to get going, there is nothing peculiar about running it and it has been seemingly quite reliable. I have even thought of other fantastic uses besides providing quick little help videos and really, the limits of this application are at the limits of your imagination with this tool.

openSUSE Linux and all it’s fantastic tools add just a bit of happiness to my life, and I am so incredibly grateful to everyone that has had even the smallest part in making this possible.

Virtual Machine Manager with QEMU/KVM on openSUSE Tumbleweed

One of the beauties of a rolling distribution is that sometimes you are forced to use a new piece of software… My regular Virtual Machine application, VirtualBox was non-functional for a few days due to a kernel update and some sort of mismatch with the kernel driver or something… The positive is, I got to know a new Virtual Machine Application, Libvirt with QEMU/KVM. Quite honestly, I am not even sure what to call the application stack. The application is virt-manager which is libvirt and the application title bar is Virtual Machine Manager so maybe it goes by them all or I can’t make heads or tails out of the name.

Installation

I found I had to install a few things to make this work.

sudo zypper install libvirt qemu virt-manager libvirt-daemon-driver-qemu

Setup

Set up my first virtual machine. After doing a little reading and digging to figure out what was the best solution for me in my use case, which is, on a desktop testing other distributions or software in a virtual machine. This is how I set it up.

Initially, you have to Add a connection. Depending on how your system is out of the gate, or if you canceled this operation. Here is how you get back to it.

File > Add Connection…

Virt-Manager-01-Add Connection

For my purposes, I am using the QEMU/KVM user session as the Hypervisor. I also selected the Autoconnect tick box to ensure that when I started Virt-Manager, it would make this connection.

Next step is to create a new virtual machine. Since I am installing from an ISO, I selected the first option. If you are running a 32 bit version of Linux, you can select that architecture instead. Although I have not played with this as much, my understanding is you can use other CPU architectures here as well.

Virt-Manager-02-New VM

Unless you have already selected the media, it is at this point you can Browse to select the ISO you have downloaded.

Virt-Manager-03-New VM

Select the Brows Local button at the bottom of this window to search your file system for the ISO of choice.

Virt-Manager-04-ISO

The application will generally automatically detect the distribution, if it is not detecting it you can manually search or find a “similar” upstream project.

Virt-Manager-05-ISO

Next step is to set the memory and CPU. I elected to use two CPU cores.

Virt-Manager-06-Memory and CPU

The next step is to either select or create a disk image. In this case, I am using the default Create a disk image for the virtual machine of 32 GiB. It should be noted. Unlike VirtualBox, these disk images are static allocations for the size you set. They do not dynamically size based on the amount of used space on the virtual disk.

Virt-Manager-07-Storage Volume

The final step you are ready to begin the installation. Modify the name, customize the configuration and change the network selection if you see fit. I just use the Usermode networking. For my purposes this works fine.

Virt-Manager-08-Summary

Upon selecting finish, a new window will open and the ISO you selected should boot up. Since openSUSE booted just fine, any good operating system will work similarly.

Virt-Manager-08-GRUB Boot

Configuration

When you open but not begin running a Virtual Machine you have the ability to make modifications to the Virtual Machine Hardware. As compared to VirtualBox, it feels like you have a lot more control and also a lot more ways to have the VM misconfigured and not behave as you would like. Your mileage my vary.

 

Should you want to make changes to the number of CPUs, Memory or any of the graphics and network settings can be adjusted to suit your needs. I did not alter much of anything here. In order to make the video adjust as I would like in Plasma, I set the Display Spice type to Spice server and Video model should be set to QXL.

 

This will allow me to take full advantage of whatever screen real estate I have available.

Virt-Manager-16-Adjusting Plasma for monitor.png

This is also the part of the post you can point and laugh at my old, non-high-DPI screens to which I will respond, “my old hardware still works, thank you very much.”

What I Like

Qemu with Libvirt just feels much faster than Virtualbox. It has a kind of raw, running on “bare metal” feel as opposed to that slightly sluggish virtualized feel to which I am more accustomed. I do appreciate this performance enhancement. I do have to preface that this is not the experience I get from all desktop environments but Plasma does run quite well.

The interface, although initially a bit overwhelming, is pretty great. I am not going to go into detail on all the features as most of the time, the defaults work well for my use cases.

I don’t have any issues with any updates that roll down breaking this utility. I am not completely sure of the technical reasons as to why but it seems as though this project is less affected by updates to the Linux Kernel.

What I Don’t Like

Virtual Manager is a GTK application so it is not as nice looking as the Virtualbox Qt, although at the time of writing this, I see there is a project on Github called qt-virt-manager.

There isn’t an option to have a dynamically resizing disk so I have to be more careful with the number of disk images I keep on my primary drive in my /home directory. Thankfully a little bit of symbolic linking to a 3rd, removable, drive and all the qcow2 files are available. It is a bit of extra work but worth it for the reliability and increased performance Virtual Machine Manger provides.

The name of this application stack is a bit confusing. I don’t really know what to call it. I learned of it as Libvirt, libvirt is the name of the directory that houses my virtual machine drives (~/.local/share/libvirt). Just knowing Libvirt didn’t answer how to get it going as it wasn’t called that in the repositories so a bit of searching and reading documentation I was able to get it all together in my head and take some notes. So, I think the confusing name and the barrier to entry did make it a bit challenging but I appreciated the journey to get me to this point.

Final Thoughts

Virtual Machine Manager is a great, reliable tool that appears unaffected by changes of the affects of a rolling distribution. It is, in some ways, a bit more difficult to set up, but once you understand that the “Add Connection” portion and set up the QEMU/KVM user session, the simplest Hypervisor. You are good to go. There is so much more you can do with Libvirt and it’s components. I am only barely scratching the surface of its capabilities.

Although the disk allocation is not as convenient in Virtual Machine Manager, it is easy enough to manage using additional storage and it also keeps me from allowing too many unused machines from littering my computer.

Ultimately, this won’t keep me from using Virtualbox but it does give me another tool to play around with and try stuff out. I am very appreciative of everyone involved in making this tool reliable and easily used for the average Linux user. I am especially grateful that this application stack is more tolerant to the rolling release model that is Tumbleweed.

Distracted by LeoCAD Once Again on openSUSE Linux

LeoCAD-01-Title

LeoCAD is an application that I use somewhat frequently. It is available for Linux, Windows and even Mac but I don’t have a Windows or Mac machine of which to compare to Linux. I have written about the joys of using LeoCAD before if you are interested in that blathering and at that time I used the AppImage to run the application. Now am using the openSUSE community repository instead and I installed it from here:

https://software.opensuse.org/package/leocad

The downside of using this source is, you do have to manually install the parts library to a location on root.

/usr/share/leocad/

The parts library can be found here.

I did have some issue getting LeoCAD to find my library but but naming it library.bin and placing it in the aforementioned location made the parts available.

What I particularly enjoyed about using it from the openSUSE repositories is that LeoCAD now respects my dark desktop theme which is much easier on my eyes and more enjoyable in which to “work.” Okay, I realize, I am “playing” and not “working” but it is also a fantastic teaching tool.

The version of LeoCAD I am using at the time of writing is 18.02. It works very smooth, has yet to crash and is a joy to use.

Designing

Designing my be a stretch, actually, more like modification of existing designs. A little back story, 8 year old me was incredibly enamored with this LEGO space theme called Blacktron. I didn’t like that LEGO considered them the “bad guys” and that idea has perpetuated with, for what I can tell, no variation on that meme. So, I have decided that I wanted to introduce that idea, that they are not still the “bad guys.” I did this by making a couple Rebrickable.com submissions with a different idea, here.

One of my first “designs” was just making this first Blacktron LEGO set the way I wanted it as a kid. It included reversing the connections and modernizing it with the newer small parts to add more interesting detail that is now available.

One of the features of this and the Blacktron vehicle sets was this modularity that was advertised on the back of the instruction manual. I didn’t like that the Invader connectors were “backwards” from the other vehicles so reversing it was a must which also made for some space to add some other details below the wings.

Blacktron Combining Options

In changing the direction of the Technic connectors, I was able to make the interaction with the other models more to my liking. The original intent was fine but I just happen to like my revision better.

Since there is this modularity as part of the design with the Invader it essentially giving you two options of play with this set: with the cargo module and without, a “scout mode,”  I thought, “what if the Invader was a multi-purpose, multi-role craft?”

So, I took another existing design from another space theme and incorporated the elements into the Invader as a module. Another theme I enjoyed as a child was this M:Tron theme. They had all these cool magnet features that I think was far more popular than what the Blacktron Theme had ever been. The process I used to build this was to cobble together the idea with the parts I had than take the design to the CAD to optimize the design and order more appropriate parts.

Invader Crane Mode-17-Module

Upon receiving the parts, I made the adjustments and the final test was giving it to my 4 year old to see how long it would stay together. The good news is, it appears to be a success and brought a lot of smiles to my kids. The Crane portion does seem to get ripped off a bit more than I would like but no more than the original model, perhaps a little less than the original model but not my much.

I have other “designs” that have been inspired by Star Wars but those will have to wait another day. This blathering about playing with children’s toys has gone on long enough.

Final Thoughts

Using LeoCAD and the real thing allows me to teach my kids the product design process but in a much shorter cycle and in a more fun way, with LEGO. We will build an idea, take it to LeoCAD and go back and forth between real LEGO to the CAD and back to the LEGO again to test and refine the design. I can demonstrate what it is like going through a product development cycle but with a much, much shorter design validation cycle. That design validation is, will it hold up long enough in the hands of a 4, 6 or 8 year old.

Dolphin | My File Manager of Choice on openSUSE

Dolphin File Manager

Managing files is nothing new for me. Since my days on the Amiga Workbench of the early 90s, I have developed a preference for how I like to manage my files. My first real exposure to what I think is a fantastic file manager was “Midnight Commander” to which a mode of that was available using Konqueror in the KDE 3 days. It might have been there in KDE 4, I can’t recall because it was about that time KDE introduced the best file manager I have ever used. Dolphin.

This is my rather biased view on why I think Dolphin is the best file manager available. To give you an opportunity to bail out of this blathering here, I’ll sum it up in saying, this, Dolphin is the best file manager based on its flexibility, speed and KIO plugin functionality that allows me to manage files on remote machines with little effort. It just does its job in a fantastically reliable, smooth and intuitive manner that I really appreciate. It only lacks one function that does require me to go back to Konqueror from time to time.

I had originally planned to be a part of the discussion concerning File Managers on the BigDaddyLinux Live Show but was not able to participate. You can watch the discussion here.

Scope of this Blathering

I am not going to compare Dolphin to another file manager. This is not a persuasion to use Dolphin in any way. It is merely highlighting the features I use regularly and greatly appreciate. Ultimately, I believe you have to use what works best for you and your situation.

Briefly About Dolphin

Dolphin is the default file manager in KDE Plasma. It is simple and easy to use for basic functions that any user with even a limited understanding in file management can understand. The file manager’s left-side pane gives you quick access to places you visit, either local or remote at a click away. It contains, search functions using Baloo File Indexer that allows for very rapid locating of files. Another great feature is the ability to easily find recently saved items as well.

The main portion of the interface is where you interact with the files themselves with some useful hot-spots for selecting multiple files for those that prefer the single-click to open files and folders.

On the right, there is an optional panel that gives you details about the current folder you are in or whatever file(s) you have selected with even the option to add comments to things. If you want to preview some media, selecting the file and pressing play will in that pane provides that feature as well.

Everything in Dolphin can be customized to match your particular preference. There are limitations, of course but I don’t seem to bump into those too much.

Top Five Fantastic Features

1. The Interface

The look of Dolphin, especially with the Dark Theme I have chosen just looks good. It is clean and feels polished. It gives me everything I need to navigate quickly to whatever location I need to go to get what I want. As briefly described. The Places and Information side panes on either side can be easily turned on and off by pressing F9 or F11, respectively. F10 to create a new folder and several others I use. Function Keys are well utilized with this file manager and that makes for a pleasant and efficient user experience. Dolphin has tabs, tabs are just fantastic and when I was first exposed to Tabs in Konqueror in 2003, there was no going back to separate windows for each file location. It is such a fantastically clean way to keep your fingers on multiple locations.

Dolphin-01

2. Split Windows.

With a Simple strike of the F3 key, you cRather than open another Dolphin Window, there is an option to split the view into two views. This makes for easy comparison of files and folders within different directories and moving them around accordingly. I often have a Tab or two open that has the window split for easy management of files. This is a bit of a callback to the Midnight Commander days of old.

Dolphin-02-Split

3. Filter Bar

This is a feature I use often when I have those directories that have a lot of files in it and reading through each of them would take too long. To activate this feature, Alt+I or Control > Tools > Show Filter bar if you would prefer to click your way there. One such way I use this is to search through my media folders for specific artists of songs or movie title. I also use this to sort though my camera files for specific dates. This feature has spoiled me and I can no longer consider any file manager that doesn’t have this feature.

Dolphin-05-Filter

4. Search Function

This is heavily tied into the KDE Plasma file indexing agent and I don’t actually know if it works without it activated but the splendid feature is a great way to look for anything sitting in your file system. I have used this to locate old records of a specific title successfully countless times. I can’t say enough good things about file searching in Dolphin coupled with Plasma.

Dolphin-04-Search

5. Terminal

Last, but certainly not least is the ability to open up a terminal with a quick reach to F4 at the same file location of which you are working. To exemplify this feature, if I am in my CubicleNate directory the terminal opens to ~/Documents/CubicleNate and I can do whatever functions, in the terminal from my working directory. Also note, if I jump to another tab or the adjacent split window. The terminal jumps to that directory. It is hugely useful and a welcome feature. It makes the terminal even more accessible and another tool readily available to aid you in making your work more efficient.

Dolphin-03-Split with Terminal

Final Thoughts

Dolphin is a great file manager that works so well, I am not sure where they can go from here… except for one small feature that keeps me going back to Konqueror, File Size View. It is a graphical view of the working directory that visually shows the size of each file or folder recursively. This is a great way to visually see what is consuming your file system (I almost wrote hard drive). This is not a daily usage feature but it is something I go to from time to time to lean out some of my project directories. I can easily find backups or repeats of large backups of projects that can be weeded out.

I am not sure how well Dolphin would work on a GTK based system or if there are features in parity to what is available in Dolphin but I can say that Dolphin is my “killer app” when it comes to what drives my Desktop Choice. It is the best looking, feature rich file manager I have ever used. I wholeheartedly believe it should be the standard for which all file managers strive to propel Desktop Linux forward.

KDE Plasma 5.15.0 on openSUSE Tumbleweed

There has been quite a lot of buzz in the news about the first stable release of Plasma in 2019, version 5.15.0, released on 12 February 2019. It came to openSUSE Tumbleweed a few days later and a few days after that, I started updating my various systems running Tumbleweed. I am not going to cover all the changes and improvements, there is plenty of that available to read. Instead, this is my experience with the upgrade process on the first three Tumbleweed machines.

My primary machine isn’t generally first to get the latest updates, because I am using it nearly all the time so I will begin the updates on other machines, incidentally, all of which are Dell. The first machine that I performed the updates is a Dell Latitude E6440. There isn’t a whole lot of software on this one as it’s primary focus is for educational related activities. There aren’t any community repositories on this machine so the update required no intervention at all. The next machine, a Dell Inspiron 20 3048, does do a lot for me but doesn’t have too many community maintained repositories. It too went without incident. Lastly, my primary machine, also a Dell Latitude E6440 but with more memory, storage and a dedicated AMD GPU.

This machine has quite a bit of software on it. I do try things out but I don’t always remove the applications or community maintained repositories. It took it as an opportunity to start trimming out some additional repositories, thankfully, zypper makes that process easy. My primary machine was trimmed down to 36 repositories. Then I performed the update.

sudo zypper dup

Zypper ran through, did its thing, asked me about a couple python packages an one package I installed that I already knew was “broken” by not having a dependency. After Zypper calculated everything out and I agreed to the update. Just as every other Tumbleweed update goes, this one proceeded without incident.

All three machines had but only one small issue. They didn’t want to leave Plasma to reboot, specifically, selecting “reboot” or “halt” and even “logout” did not actually perform those actions, Instead, I ran in terminal:

sudo systemctl reboot

There may be a better way of doing a reboot, if you are aware of such, please let me know. A few moments later, the machine started up without incident and what I may be most excited about is that, everything still, just works.

KDE Plasma Upgrade 5.15.0 KInfoCenter

I did receive one pleasant surprise, my Bluetooth keyboard, for the first time communicated that it was low on power instead of just going unresponsive. I was able to see a “10% Warning” pop up notification. I thought that was pretty slick. I have been enjoying the status and warnings with wireless Logitech devices for years but this was the first for Bluetooth. Very well done.

Final Thoughts

Nothing is ever perfect but my experience with using openSUSE Tumbleweed has been pretty fantastic for the last two years. I don’t have to worry about an update breaking my system or crossing my fingers when the operating system base iterates to a new version. Not a single piece of software has broken or had any regressions. The two applications I check for issues, Kdenlive and the Open Broadcaster Studio, continue to work just the same. I experienced zero appreciable downtime with this update which is another tribute to all those involved with openSUSE, KDE Plasma and ever other application so many graciously pour their energy into and permitting me the use of this finely engineered, fantastic distribution of Linux.

Right-to-Left Script in LibreOffice using KDE Plasma on openSUSE

Text Icon

In case you have to mix right-to-left text into your documents and you aren’t sure how to make it happen, it is super easy to do with LibreOffice when running in concert with openSUSE with KDE Plasma as the desktop environment. You’ll have to check with your Desktop Environment for how to add additional keymaps and how to switch between them.

Instructions in Short Form

On KDE Plasma, open SystemSettings, select the Input Devices Module. Under the Keyboard sub-module, select the Layouts tab. In the Layouts Indicator, activate Show layout indicator and take note of Shortcut(s) for Switching Layout. In my case, it is Ctrl+Alt+K

Toggle the Configure layouts, then +Add the desired layout. From there, open the text editor of your choice, like LibreOffice and start typing away. Switch the layouts through either the indicator or the keyboard shortcut. You’ll be happily amazed by how well it works across multiple applications.

A Little Video to Demonstrate

Mostly as an excuse to play with Kdenlive and SimpleScreenRecorder, I made a video of how to do switch your layouts on the fly and write. Unfortunately, I don’t have the physical character layout on my keyboard and I was too lazy to figure it out and demonstrate a proper Arabic sentence.

Final Thoughts

One of the features I have enjoyed for many years working with the Linux and KDE [Plasma] has been the absolutely fantastic flexibility to allow me to get whatever work done that is required of me. I have had to use the switching keymaps on numerous occasions and the dynamic switching to those keymaps is absolutely a must. It’s just another way that Linux has made my life easier.

Rambox | Chat Message Unification Application for openSUSE

Rambox on openSUSE

Not long ago, I started using Franz, a chat messaging unification application and I had a good experience with it. I had talked to a few e-friends about it and some advised me that I should also try Rambox. Since I had just installed Franz, I wasn’t about to try something else, not yet anyway. After some time of very happily using Franz, something had happened and it wouldn’t start. Since I was using a community repository and I could have very well chosen another community repository and kept going but it was time to try this Rambox all the kids have been talking about. So I did.

Installation

Like anything else in openSUSE, the installation is easy, just search and install. Since I did that part, you can just check here:

https://software.opensuse.org/package/rambox

Once the installation is complete. A menu entry will appear under the “Internet” category. Click there or whatever method you see fit.

How It Runs

The application runs well and it is as intuitive as one would expect. The difference that I noticed, as compared to Franz, is that having an account with an external service is optional. Franz requires you to sign into their service in order to use their software and in doing so, synchronizes all your systems that are running Franz. This is quite handy. Rambox too as this option but it is not compulsory.

Rambox-01-Start Screen

Rambox has many built in options for services for you to configure. In fact it has more service options than Franz does, most notably, Mastodon. If there is a particular service you want and it is not available, you have the option to add a custom service. This was particularly handy as Rambox does not have a Google Calendar service.

Rambox has several customization features to it. Notably, there is application behavior for notifications, a hardware acceleration feature and start automatically on system startup.

Rambox-02-Settings.png

The customization feature I do appreciate is the service bar location. I put the bar along the left, as opposed to the top… no speculation on that location necessary.

Adding a service is incredibly straight forward. Select the service you want and fill in all the necessary bits. After you add the new service to the application, it will appear on the service bar.

Rambox-03-Add service

The order of applications can be reordered to your hearts content and services eliminated if they are no longer desired in this application. It is incredibly flexible. In this manner.

Overall, this This application works very well and I intend on using it a bit longer and do some more comparisons to determine if I will continue using it or go back to Franz.

There are cases that a service doesn’t start or restart when network access is lost and reestablished. There is an option to Reload offending service or reload all of Rambox. Under the View menu.

What I Like

When comparing it to Franz, the feature that I appreciate the most is the ability to enter a custom service. In my case, I added the Google Calendar account related to my employer.

Like Franz, this is a fantastic message unification application. that has a lower memory footprint than using a browser. Rambox uses just under 1.8 GiB for 12 services which shakes out to about 150 MiB per service. I still think this is far too much for what they are doing but not being an expert in this area, I couldn’t tell you why.

Having one application that has all my messaging applications consolidated is very handy. It has a nice notification applet that lets you know when you have a new message on any of your services and mute the notifications if necessary. It should be noted, if you mute your notifications, you won’t hear anything within each service, like an inline video.

Lastly, the option to Synchronize your configuration or not is a handy feature. You can push or pull your configuration as you see fit for each machine. I didn’t try pushing two different configurations to see how that might affect each client.

What I Don’t Like

There is a lack of Dark Theme. I would much prefer that service bar have a dark background to fit the rest of my desktop theme but that is a small potatoes item.

The user interface on the application for the settings or adding another service just do not seem to have that nice modern look as you’d see on Plasma. When loading or saving, the application brings up the GTK File Dialog of which I am not particularly fond.

The biggest sore spot for Rambox is that it does not have a spell check. This is the one area where Franz excels. It is also the only area where Rambox falls short. Outside of that, it is a pretty fantastic application.

Final Thoughts

Rambox is a fine application that I enjoy using. It works well and is more convenient than using a web browser. It also seems to use less memory than a browser so that is also a plus. I don’t know or understand the mechanics as to why but even at approximately 150 MiB per application does seem a bit steep for something that just sends text messages.

If Rambox is an application that works well for you consider supporting the project or if it improves your work flow, try out the Rambox Pro. The application may be free but it isn’t free to make.

For the time being, I am going to continue to use Rambox on my primary machine and Franz on another machine just to see how it shakes out over time. If you are running multiple chat clients and don’t want to authenticate with a third party service, Rambox just might be the application for you.

Coherent Color Scheme Creation for Qt and GTK on openSUSE

I might be pushing it just a bit by saying I “created” a scheme as I just took two color schemes, Breese Dark and openSUSEdarkalternate, and created one [subjectively] better theme based on those two. I happen to like the green accents in the openSUSE Workspace Theme and the Breeze Dark Theme looks pretty good but the mix of blue and green accents makes me less happy. I have been using the openSUSEdarkalternate theme for quite some time until I discovered an issue with one application.

Why take the time?

A couple reasons. For starters, the Breeze Dark GTK theme has been using blue highlights, which has been fine. The tipping point was when I was trying my hand in doing video editing with Kdenlive, I sort of bumped into a problem. The dark color scheme, openSUSEdarkalternate, did not play well so I had to switch it with the built in Breeze Dark scheme in order to be able to see all the icons and things. As nice as the stock Breeze Dark theme is, I really want those openSUSE green highlights and now more of my desktop was a mixture of themes. I was now compelled to unify the appearance of my desktop, especially after noodling around with ElementaryOS and seeing how much emphasis was put on its appearance. I wanted my choice of desktop to have a more unified but not exactly vanilla Plasma look to it. I wanted a unified openSUSE Theme.

The Solution

First was to ensure that all my KDE Plasma applications had a unified look. My first step was to take screenshots of the different green RGB color-values used in the openSUSEdarkalternate scheme. The green in that theme is just the hue and vibrance that is subtle and pleasant so it was imperative that I used the same colors. The absolutely fantastic feature of KDE Plasma as well as the related desktops preceding it is the ability to customize it to your hearts content. The tools are already there and ready for you to tweak. A testament to what makes Plasma great.

To start, open the KDE Plasma SystemSettings, then the Colors module under the Appearance section.

KDE Plasma SystemSettings

The Application Color Scheme tool has several schemes from which to choose. My first step was to open the openSUSEdarkalternate theme and take note of the RGB values of the different green colors used. I cheated and used the screenshot utility Spectacle to accomplish this. There were a total of four different green colors used.

I then opened the Breeze Dark theme and started changed all the relevant blue colors to the equivalent green colors.

I only had to adjust the Common Colors section. It seems that any of the other sections are using the same Color Identifications. When I was complete, I saved this scheme as openSUSE Breeze Dark and applied the changes.

It looked good, but then I was still left with the GTK theme to change. I planned to do similar in Plasma as I did for GTK. Unfortunately, customizing color schemes in GTK is not baked in like it is Plasma so it was time to do some searching and I came upon this application called Oomox. There is no official openSUSE package but the fantastic openSUSE community maintains the package and it can be installed from here:

https://software.opensuse.org/package/oomox

Choose whichever community member maintained package you wish. Oomox does require one other package in order to run: gdk-pixbuf-devel

sudo zypper in gdk-pixbuf-devel

I was not able to import the Breeze Dark GTK theme so I just had to create what I wanted manually. It should be noted that such a feature has been requested. Good bad or otherwise, GTK color schemes are easier to create from scratch because there are fewer color in a theme.

Oomox Color Theme Customizer

Not pictured but there is a Roundness theme option so I modified that to match about what the Breeze theme is and set that parameter to 3. I thought that was an interesting setting to have and I quite enjoyed playing with it. Ommox is a very interesting piece of software and I recommend you to play around with it, just for fun.

It took four iterations of playing with the theme to get it right. I tested using Gnome-Recipes and Firefox to see that the scheme looked correct to my untrained eye.

Gnome-Recipes openSUSE Breeze Dark

My only criticism at this point is the GTK2 Theme is a bit blocky looking. I am not sure why, exactly. It just looks somewhat out of place against the Qt and GTK3 widget. I don’t think it’s a big deal but if anyone has any suggestions on that, I am open to anything you can offer.

Since I am happy with the theme and added to my openSUSE Linux page to download. I will eventually create a package hosted on OBS when I can take the time to do that properly.

Final Thoughts

Having exact color schemes hasn’t really been a thing for me, so long as it was close enough. Due to playing around with Elementary OS and seeing how everything is so well thought out, I started looking a bit more closely my desktop and thought, how can I make things look more deliberate? I am exceptionally pleased with the results and I think I may have also decided to go all in on Breeze Dark + openSUSE green. I even retired the Oxygen Window Decorations in favor of the Breeze Theme so that it better matches the GTK widgets. Everything seems nicely coherent. This is the most satisfied I have ever been with a desktop environment, ever.
