Plasmashell crashing every login

Everytime I login (Tumbleweed/KDE), for the past couple of weeks, I get this message:


Anyone else.
Any fix?
Thanks.

Did you try:

Please report this error to help improve this software.

And the Report Bug button ?

Tells me I can’t report bug:


But was basically wondering if it is a ā€œjust meā€ issue, anyway…

You can report a bug manually to bugs.kde.org for plasma by providing the ā€œDeveloper Informationā€ provided by this utility.

It does not matter if it is just you, plasmashell isn’t supposed to crash, on start.

You didn’t give any other information as to the circumstances this happens, so only the ā€œdeveloper Informationā€ (i.e stack trace) will tell us what is this crash origin and will allow to determine how many users have encountered it.

Hi all,
some experiences from the last days/week from my side.
I’m using Plasma 6 on Fedora 41, Lenovo laptop Z13 Gen1.
Since two days, lot of crashes with plasmashell and some other crashes. Before it started, I’ve changed to GNOME session yesterday, coming back to Plasma, the language of the keyboard changed, crashes every 5 - 10 seconds of plasmashell, system asking for which backend to use (opengl, vulkan, …). Problems partly solved by rebooting (keyboard language), but the issues with crashing plasmashell remains. A small overview:


Don’t know what to do, no problems with GNOME, crashes with Plasma and not rally usable. Sudden ā€˜blackouts’ of the display and recovering within 1-2 seconds, abrt-dialogue afterwards.
Does someone has similliar experiences at the moment? Of course, I can work with GNOME, but …

Make sure you’ve updated to the latest plasma-workspace package, there was a bad issue with plasmashell couple weeks back. I was bad enough that I could not log into KDE at all so I worked around it by setting the login manager to GDM and I used KDE/Xorg instead of KDE/Wayland. The bug was wayland specific. Then an updated KDE plasma-workspace package came out that fixed it. This was on Fedora

Sorry to barge in. It’s not very clear by reading the message but do you have both Plasma and Gnome installed on the same Fedora installation?

Yes, have both on my TUMBLEWEED install, and always have…

I see. The few times that I tried in the past (when X11 was still the default display server for Fedora) to install both DEs, I also had various issues, especially with the keyboard shortcuts not working in the Plasma session and setting mismatches, among other things. Evidently, Tumbleweed must handle something differently. I honestly thought it was unadvised to install both DEs alongside each other.

Same to me. Both installed on the laptop. Started with GNOME on F36, parallel installation of Plasma several months ago with F40. Not so much trouble until few weeks ago. In addition, Lenovo/Fedora is messing up device BIOS/UEFI nearly 3 times a week. Currently, dmesg asks me in the first lines of the output to report failed microcode installation. Lot of trouble with this device.
Yesterday, I’ve also had a plasmashell failure right after login.

I haven’t seen this one for a long time.

I did have a niggly problem with icons, not only resetting their position - but also not showing custom icons until after I select, context menu and escape…

Anyway, as always, most Plasma bugs are PEBCAK bugs - so the first couple of steps are these:

  1. Create TEST user, log in, test it there… usually that’s clear - and if it isn’t, then it’s not your files or settings (so it’s a real problem).
  2. Post here, give any information requested - inxi/journals etc to find out the problem.

If TEST user was clear, then there’s no bug - so you can now rename your .config to .configFORKED and log out/in to see if THAT clears it.

If that does clear it, then copy back piece by piece.

My latest problem was something Plasma didn’t like in my plasma-org.kde.plasma.desktop-appletsrc - so basically I got most of my config back, then had to set up panels/desktop slideshow and mouse actions and I’m good to go…

You can try to be more targeted and organised (config’s a big folder) like this:

mv .config/plasma* ~/.config/backup_plasma/
mv ~/.config/kdeglobals ~/.config/backup_kdeglobals

However, I’m clumbsy - I just move the whole thing - then select and move MOST things back (nearly all folders are safe anyways) and after doing a quick log out/in again, I’ll move half what’s left - doesn’t take more than 3-4 goes at best to have it narrowed down; just make sure you count/remember the last bunch moved… as you’ll be wanting to move half that back if you can’t start making good guesses.

Hi ben2talk,
your suggestion of using a test user makes me smile: I’ve tested an existing administration account (never used with Plasma) on my laptop. And? No more crashes in plasmashell, it’s running perfectly as my personal account was before.
Thanks for the tipp. Now it’s on me to grab for differences and error sources.

Differences I’ve directly recognized are with the application bar (colours) and some minor differences. But it’s working as before

Ummm…
Would appear that whatever it was, has been fixed…?
Just did an update, and noticed there were several ā€œplamaxxxā€ updates.
workspace/desktop/session/addons…

All good.

I’ve had an update (a big one including firmware, microcode etc, approx. 2 Gb in total) before the crash of plasmashell starts repeatedly. Update was progressing in background and I remember that I didn’t reboot before changing to GNOME and finally back to Plasma. Maybe this was the error? But ok, I was able to restore most of my configs. I’m using Plasma nearly right out of the box, only some minor changes were necessary. But I also noticed that Snapper was not logging correctly because I didn’t respect migration from dnf4 to dnf5 in F41 meaning to easy rollback was possible.
Up to now, nearly everything is running smooth.
