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.

There is a bug that is open right now which sounds like it might be one you were experiencing or possibly explains part of the issues.

https://bugs.kde.org/show_bug.cgi?id=501073

Like the web browsing might have been from middle clicking, which causes a lengthy hang and resuming from suspend and powerdevil are a prime suspect for it.

The login wait might be an issue I vaguely recall about the splash screen and that disabling it removed the startup hang.

I’ve been exclusively using Manjaro KDE since September of 2021 and the linked issue I started getting a couple months ago and it’s gotten bad enough to make me want to start hopping again.

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.

Well, before wayland I always used fluxbox (eventually with picom compositor, which previously was compton). Then now on wayland I’m using sway with fuzzel, yambar and others.

I’ve always felt both gnome and kde, as well as most other DEs really bloated. Gnome used to be more stable on wayland, and as of Today with better support for nvidia AFAIK, but KDE is quickly catching up.

Not sure why the hate on gnome (and I guess on GTK as well). It doesn’t offer all the customization by default, but you can get it through extensions while available. But on KDE one really needs to see a pletora of dependencies each time one adds a simple module or application. Both are improving gradually to become less intense on resources being KDE more advanced on that.

But hey, both are bloated compared to non full DE compositors such as sway or labwc. BTW I use sway with tabbed mode (not actually tiling) and some tweaks, and I prefer that over stacking compositors, but if wanting one labwc is pretty cool.

On X11 there’s a huge amount of window managers plus compositors plus several other applications which altogether can give a similar sense to a DE but way less intense on resources, and for sure way less bloated. To me DEs are overrated to answer your title, but perhaps that’s just me, :)

I have non of the issue on my Starlite (Kubuntu)

My PC with the newest Arch Linux seems to have sometimes issues with sleep and freezing on waking up. (Intel CPU + AMD GPU)

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.

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.

I’ve used it on Endeavour for about a year and on Tumbleweed for eight years before that with no real problems other than plasma-shell occasionally restarting. I have Nvidia and the open drivers.

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…

Look at the reddit called “unixporn” and search for Xfce. You ll see what’s possible with Xfce. For me the KDE crashes are a dealbreaker. My Xfce setup is so simplified, that nothing can be ugly. I use Bspwm for the windows and stripped down Xfce panel (dont touch third party status bars, such as polybar, its waste of time if you already have Xfce). No menu such as Whisker menu, but Rofi instead. I got Xfce stability without the old looking.
