🐧 Dedoimedo is high!
Dedoimedo just did it: Kubuntu 26.04 upgrade on a 2014 laptop went superbly well:

Excellent news! Everything is better than in 24.04. For realz.

Snapd correctly remembered my snap connections, which is also quite important.

Suspend & resume works fine. All of the hardware is correctly detected, initialized and used. The performance is spectacular. Kubuntu 26.04 is more responsive than its predecessor, and even with compositing still on. I haven't tested any newer kernels, but 7.0 does the job quite well, and I presume, if there are HWE updates, that I will gain still more speed in the process.

Conclusion
I am very, very happy. I can say that this is probably the pinnacle of my Linux experience in 2026. The upgrade process from Kubuntu 24.04 to 26.04 was fantastic. It was fast, largely painless, mostly bug-free, and with none of the problems I encountered doing the previous LTS-gen upgrade. On top of that, my system is now faster, leaner than before, despite its advanced age. Kubuntu 26.04 brings in a fresh breath of air to my aging silicon. And on top of all that, I managed to achieve all this using the X11 session, with hybrid graphics to boot.

Three, all of my software works. Nothing broke. The performance is great, and better than expected. The system is more responsive than ever. I've yet to encounter any hardware-related issues, and there probably won't be any. The only downside is an aging battery, but that's easy to solve really. All in all, it's as if someone has gifted me a brand new machine. What else could anyone ask for? Indeed, I only have praise, this time around. Well-deserved praise. This probably means, next time I feel grumpy, I must remember that Linux for old hardware promise is still valid, most of the time. Forget any fancy new atomic distros and such. Grab your classic image, and enjoy it. Plus, when you think about it, you also have to give some praise to Ubuntu, too, because I'm quite certain the combo of good and long support they offer surpasses anything else in the Linux desktop space. With these cheerful words, I'm out.
