Slimbook Executive report 10 & 22.04 to 24.04 LTS upgrade!

Updated: September 24, 2025

Brace yourselves. Today, I shall show you the results of my operating system upgrade on the Slimbook Executive. We shall go from Kubuntu 22.04 to 24.04, in vivo. Now, since I use the pro functionality on this system, there really isn't any urgency to do the upgrade. But as I showed you in my ninth report, I am not too happy with the software side of things. There are too many bugs, and a firmware blob delivered a while back, plus perhaps regressions in the kernel too, messed up my laptop to some degree. Occasionally, it would go into a silly loop of multiple suspend & resume cycles, the screen would blank, the keyboard would go all crazy, and then, it would return to normal. Very frustrating and pointless.

Okay, so let's do that. Perhaps Kubuntu 24.04 will make my Executive awesome again. I mean, it's a beautiful machine, but the random-beta-quality of Linux mars its capabilities. The upgrade ought to be interesting, as my system uses a lot of third-party programs. We have WINE from upstream, Chrome, Edge, VirtualBox, standalone Firefox, a couple of Flatpaks, and such. I expect all these to work seamlessly once the upgrade completes. So let's begin.

Teaser

Upgrade process

Net time: about 30 minutes. You do need to be present, because the system will ask questions. Among these, it told me how some encryption method might not be safe (ok?), how Thunderbird will become a snap, it asked me to diff or change two configuration files (GRUB and ImageMagick), and maybe there was one or two other questions. A single reboot. This is faster than Windows 11, cough cough.

If you're wondering, I ran the upgrade process from the command line, with third-party sources allowed:

sudo do-upgrade-release -allow-third-party

Now, there were a few problems and snags during the process:

Checking for a new Ubuntu release
In /etc/update-manager/release-upgrades Prompt
is set to never so upgrading is not possible.

No longer supported: gcc-12
Remove: gimp gimp-gmic iftop kdenlive nethogs winehq-stable winetricks

Removing libssl3:i386 (3.0.2-0ubuntu1.19) ...
dpkg: libssl3:amd64: dependency problems, but removing anyway as you requested:
x11vnc depends on libssl3 (>= 3.0.0~~alpha1).
wpasupplicant depends on libssl3 (>= 3.0.0~~alpha1).
wget depends on libssl3 (>= 3.0.0~~alpha1).
virtualbox-7.0 depends on libssl3 (>= 3.0.0~~alpha1).

Results ...

Good news, the upgrade completed successfully. My machine also has a full-disk encryption, so if something had gone wrong, debugging would be quite tricky. But luckily, things were fine. But far from perfect. See those missing icons? Ah.

OK, so let's me tell you what's changed and what didn't work:

Now, some good things after all

It's not all bad. Following the upgrade, I can also report a few nice findings:

Smartphone support revisited

If you recall, before the upgrade, I had issues with the mounting of various devices. With Android, after connecting a phone, I had to close Dolphin and then re-open it to be able to browse folders and download files. With the iPhone, it would never show in the sidebar, and the only way to display contents was to go through the removable devices system tray menu, and select: "View photos". Now, the Android works seamlessly, so, improvement! The iPhone shows in the sidebar. Another fix. But, you still need that one specific option to be able to access the files, unless you wanna play with the command line. Overall, better than before, but still somewhat tricky. More in the future.

What about printing?

Oh boy. Well, this was still a huge pain in the nether regions. I wasted another two hours getting this fixed, and fix it I did, almost by accident. I don't think I have confidence in my own procedure. Let me tell you exactly what happened.

Printers

Why is one printer shown so many times? Three times here, four times in the ninth report.

cups-driverd failed to get PPD file - see error_log for details.

Printer finally works

However, the GUI configuration problem I showed you in the ninth report remains. If you try to configure the printer through Plasma Settings, once you click Apply, the utility will eventually crash. Fully reproducible. The screenshot below is from 22.04, but it's the exact same problem.

Utility crash

At the end of the day ...

Yes, everything works. But the upgrade was far from seamless. It was actually quite flaky. One, I had to install a whole bunch of stuff, and it's normal programs from the repos, nothing special. I mean GIMP! Two, I had to make various changes to several settings. Three, the ergonomics are worse off. Four, the printing was still a huge problem, and it has ruined my confidence.

To be fair, the laptop is cooler, works and responds a bit faster, and in the end, yes, I was able to match the functionality I used to have previously. I just resent the fact it took me several hours to get there. I would expect that from Windows or Android, not from Linux. I've done upgrades many times before, and I think this was one was the roughest so far. In general, the quality of the Linux desktop keeps steadily going down. This is alarming on so many levels.

Ready

Overall, I also find Kubuntu 24.04 ever so slightly less slick than 22.04. On their own, each individually, they are pretty nice. But for whatever reason, and this could be the specific Kubuntu theme implementation, the newer one feels a bit cruder. Not bad, but far from what I hoped for.

Conclusion

My Slimbook Executive now runs Kubuntu 24.04. The upgrade process was so-so. Fast but with interruptive questions. My configuration was mostly ported, with some weird exclusions. A bunch of programs were gone, a bunch changed, with defaults that go against my own settings. The boot sequence is not as pretty as it was before. There are lots of bugs for the .3 release. Big issues like Okular forms support and extremely buggy printing remain. You have to be quite diligent to work around them.

On the plus side, we have the speed, the responsiveness, the temperatures. Lastly, are my firmware-related problems gone? I can't say for now. Since they occur rather sporadically, we shall have to wait several weeks to see what gives. If this upgrade resolves that, I will be immensely happy, as this is the outstanding issue plaguing my laptop, and if gone, it will have made the switch to 24.04 worth it. Well, there you go. Another chapter from my Linux journey. I wish I could tell you it's all roses, but ain't so. I still have no intention of using Windows 11, I am using Linux more and more daily, but the obstacles are sometimes so severe, you really have no choice. And this irks me beyond belief. So there you are. Stay tuned for updates.
