I have been using KDE on Arch across several machines for about 3 years now, then Manjaro for a year before that. At no point have I experienced instability or issues like that. Especially that last one; I’m the sort of person who regularly has 10+ tabs open on laptops with a fraction the amount of RAM that you have.

I would say that is definitely not normal. If that happened to me, I might search online or check journalctl -b -p 3 to see if it yields any clues.

had a couple of crashes when 6 was released, but they were fixed pretty quickly and has been rock solid ever since. Those crashes probably had more to do with my nvidia card than kde itself, tbh

KDE Manjaro running on 4 or 5 of my machines, pure stability. It sounds like a hardware issue.

Here are my suggestions to diagnose this.

Option 1. Setup an ssh server, connect from a second computer (or phone via Termux), execute $journalctl -fe, and observe the journal from your second device when the crash occurs. That should help pinpoint the issue.

Option 2. If you don’t have a second device, use a non-gui tty, access via Ctrl+Alt+F1. (Usually terminals are available F1 thru F6). Once again execute $journalctl -fe and observe it during the crash.

Tbh option 2 may just be easier especially if you have minimal knowledge of ssh. Good luck, ping me back if you find this helpful and would like more perspective, and apologies if this doesn’t help you.

If the entire computer crashes, boot into a terminal and browse journalctl history of previous boots, sorry I don’t have these commands off the top of my head but if you need them and ask I will get them for you.

For what it’s worth, I experience none of that. My laptop is absolutely rock solid with KDE, it’s like a MacBook you pull it out of your backpack and it’s ready to go before I’m even done opening the screen.

My desktop is currently just over 5 days of continuous uptime (no sleep). I’ve crashed more often because of ZFS than KDE.

Both are ArchLinux. I also have a friend on Bazzite that doesn’t have issues with KDE either, and it runs great in my VM.

Those all sound like possible graphics driver issues.

Those aren’t normal issues.
It sounds more like a driver or hardware issue which may only pop up in KDE (Wayland) and not in your other WMs (X11).
As a first step, try logging into the KDE (X11) Session and see if it still happens.

Do you have an nvidia GPU? It’s the most important thing to know.

Is KDE actually good or it is overrated?

That’s like a trick question 😀
If I say it’s good, and that contradicts your own experience with it, you can say “see it’s overrated, people say it’s good, but in fact I know it sucks.”

I use it on Arch but I’ve seen people using it on Fedora and it looked good and stable.

Did you try to look into it, see what’s causing the problems?
In my experience having used Linux and KDE Plasma for about a decade now, if you wanna have a good time you’re going to have to figure stuff out, check the logs, troubleshoot, look it up online, etc.
If you expect to go through different distros to find one that “just works” you’ll be disappointed, and you’ll be wasting your time. Issues can be hardware-specific, maybe you just need to pass a parameter to the kernel, or change a config somewhere or something like that…

I think Linux nerds are clowns who don’t understand that not everyone wants to learn what -xvf means just to extract a goddammed file.

Kde is solid and requires zero fuckery in my experience to work well. This is in fedora, suse, arch (endeavour), void.

I had issues like that about a week ago, when gaming the system was super sluggish. It turns out that an update put the render under CPU instead of GPU, as in, without hardware acceleration, or software based.

Most of those issues I do not have. By waking from suspend, do you mean hibernate? A system d update broke that last year in OpenSuse and I’m assuming other distros. I sleep now and it wakes fine.

I’ve been using Fedora KDE for…months? Maybe a year now? And I’ve yet to see it hang or crash.

Vanilla Arch is much easier to install than it used to be. Connect to wifi via terminal commands or connect ethernet, enter archinstall and go down the list.

I’ve only ever had the waking from sleep problem, but it’s consistent in other DE’s for me. I have a desktop so I just turn that and hibernate off.

I had a known problem with krunner not opening after first run unless you killed the process, but I got rofi and customized it to the teeth instead. Found out that I love rofi. I probably won’t go back to krunner even it gets fixed now.

openSUSE has the best integration of KDE, but I wouldn’t expect to see issues like yours on any distro, really…

KDE just works on my machine, which is lower specs than yours. I’ve never had it crash. I use Endeavor OS, so it came with it by default (which was part of the reason I chose it).

Edit: I don’t do much tweaking of the KDE settings other than the main color scheme. I also have never had an issue with waking from sleep on Endeavor (but I recall in years past that was an issue with most distros I tried and unrelated to KDE since I was less a fan of its style back then and didn’t use KDE). My set up is a normal desktop PC that I use daily for everything, including gaming.

I use Fedora KDE, and I don’t think ive ever seen crashes that bad on my system (AMD CPU and GPU). I used to have a small problem with RADV crashing during video playback, but that solved itself after a few updates.
