I’ve often found Kubuntu / KPE Plasma somewhat glitchy at times, perhaps caused by conflicts of settings of the options somewhere

How did I miss this thread? This is almost exactly me – unless there were problems. I feel like I spent more time on getting the OS working, instead of using the OS for work.
The problems might not have been always huge, but incredibly annoying - like once I shut down my laptop with headphones disconnected. Next time I booted with headphones already connected and that resulted in sound coming out of both speakers and headphones - almost impossible to notice something is playing for others to hear… quite embarrassing too.
Or the other time, cron just decided not to work. Or the KDE app store. Why? Who knows…

Looks like I broke Kubuntu (at least the Google Calendar Integration) trying to be clever upgrading Kubuntu 24.04 to 25.10 via the command line. 
Looks like a day off reinstalling my OS if the timeshift backup doesn’t work, or switching to something like plain old Ubuntu (or back to Mint).
And the “Details…” button does nothing…
Are you sure you need that? If your system remains bootable, and you can get into a terminal, you can fix interrupted upgrades (if that’s what happened), or anything else.
Also, going from Kubuntu or Ubuntu does not require a reinstall. It’s the same distro, just different packages.

I was able to restore my timeshift backup of Kubuntu 24.04!

Ubuntu was unable to find my network printer at home today. I print very occasionally and update very frequently, so I was unsure what broke this.
I dived into the logs of cups-browsed, avahi, and a ton of other weird stuff I prefer not to know about, only to find, 40 minutes later, that the root cause of the problem is that the printer was not under power — specifically, the C13 end of the cable became loose. 
Linux (in the form of any distribution) is not perfect, but most things like this work just fine now. When something breaks and it happens to involve a machine running Linux, why am I still assuming that Linux should be investigated first, before checking something glaringly obvious?
I guess because I started using Linux in 1998, and that time it was an uphill struggle to get stuff working, and it involved asking in forums, hunting for a kernel patch, compiling a new kernel, browsing through logfiles, fixing up Bash scripts held together by the computational equivalent of prayer and duct tape. That experience was kind of fun, but I am not missing it. It just left a mark on me.

I set up Linux Mint Xfce or MATE for my mother; has not been updated in years. Often, it takes a dozen or more hours for the print queue to clear. Rarely is it instant. No rhyme or reason; it just is.

I’ve been pondering on switching to Ubuntu Studio 26.04 when it comes out instead of Kubuntu 26.04.
Along with photo editing I dabble with ambient field recording, wildlife sound recording and video editing (mostly of my RC trucks). Perhaps an audio video orientated Distro might be a better choice, such as Ubuntu Studio compared to plain old Kubuntu and adding any needed software on top of it?
What is holding me back however is I did try Ubuntu Studio 24.04 on my old laptop. I found it very bloated (why have one virtual guitar tuning app installed by default when you can have 50!) coming with everything and the kitchen sink installed.
But then again getting real-time audio setup isn’t straightforward and at least Ubuntu Studio has that set up right out of the box.
Decisions, decisions.
With pipewire real time audio is very easy. You don’t even need fancy kernels built with special flags or anything of the sort anymore CONFIG_PREEMPT=y is the default in almost all distributed kernels and if not (like ubuntu) you can just install linux-image-lowlatency.
For low latency you just use pipewire with its jack bridges installed, and set the quantization to a low value.
I use 48khz, 32 or 64 samples, for sub 1ms latency, and it just works without any special configuration. Every plugin works, jack software works fine through the bridge, yabridgectl works, etc.

I can confirm this, I am using a software guitar amp with the tweaks you mentioned in plain vanilla Ubuntu and it works great, low latency, very smooth.

I had no idea that guitarix could now load NAM captures, that’s really cool. There isn’t really a decent NAM loader for linux so this is very welcome

Guitarix is too good in the same sense as Darktable: the software has so many exciting features that it is tempting to tweak them instead of actually playing the guitar or taking photos

What distro are you running and what software in the image? [quote=“hatsnp, post:30, topic:54725, full:true”]

Arch Linux, regular kernel, software is Bitwig but I have the same results in Reaper and Ardour using the pipewire-jack bridge I mentioned. Software age is not really an issue too, I have been using this setup for two years without a problem so even LTS distros should be good enough by now

The Stability of Discover is what drives me nuts when using KDE distros. It frequently crashes even on the smallest of things and its just slow at loading up sometimes.

Discover is a disaster. I mostly install via CLI because of it or use bazaar for browsing flatpaks.

Discover doesn’t even work on some fresh installs, it’s horrible. It later decides to work for a few days, but then stops again because idk, the constellations have shifted or something…

I can’t say I’ve had any issues with Discover on Kubuntu 24.04.
Out of interest what distro / DE are you using? Perhaps now is a good a time as any for me to do a change to something different
I’ve used MX Linux KDE & Kubuntu 24.04 & 25.10 in testing they all had issues from time to time.
