Re: KDE Plasma cannot login after update

The problem was encoutered in a newly installed Artix-runit system after first -Syyu. Switching to lightdm, configuring env variable did not help. Prompts kdewallet - then black screen.

~/.xsession-errors indicated that kwin_x11 fails to load due to a missing library (libkdecorations2.so.6).

My system uses an AMD GPU (with an NVIDIA card ignored in the x11 configuration), so it doesn't appear to be a hardware issue.

Could not start the system since yesterday's icu update, little idea whether it is related though. Considering downgrading plasma.

Regards.

Did you try to run pacman -Syu from the console? That might fix the problem.

Sure, pacman -Syu in console does not make any difference.

I have the same issue; after updating with pacman -Syyu and running also pacman -Syu from the console (Alt+F2) I get the same complaint :

Code: [Select]
kf.coreaddons: "Could not load plugin from /usr/lib/qt6/plugins/plasma/kcms/systemsettings/kcm_kwindecoration.so: Cannot load library /usr/lib/qt6/plugins/plasma/kcms/systemsettings/kcm_kwindecoration.so: libkdecorations2.so.6: cannot open shared object file: No such file or directory"

I too had this issue after updating on a fresh install. The solution that I used, suggested on page 1 was to add the Gremlins repos and locate out-of-date packages. Once Kwin and plasma-integration were updated I was able to login again.

I think the SDDM theme issue is an older bug as none of those solutions worked for me.

Is world/kdecoration 6.2.5-1 installed on your system?

Nope, I have world/kdecoration 6.3.1-1.

However, there are 3 packages left with older version:

Code: [Select]
❯ pacman -Q | grep -E '6\.2\.(4|5)'
kwin 6.2.5-3
plasma-integration 6.2.4-1
plasma5-integration 6.2.4-1

Edit: solved it by enabling system-gremlins and world-gremlins and updating with pacman -Syyu.

On a currently updated system, the Plasma problem does not reproduce.

If the problem persists for anybody then pls provide details about the packages versions, xorg logfile, etc

I didn't do any manual fiddling during the timeframe where the updates were broken, I just waited and ran -Syu as usual after, I checked the versions and kwin is the only part of kde that still seems to be on 6.2, and I still have the problem, cannot login on wayland or x11

Pls report which mirror is being used by pacman, and also try another one.

Mirrorlist generated on 2025-01-02, I just removed all the mirrors except the 3 default ones plus the czech one, ran -Syyu and no changes.

I was about to shut down the computer, but I ran it one last time, and it pulled kwin 6.3 and now the system works, I'll mark it as solved, thanks everyone for the help!

But what caused this? I saw in archive.artixlinux.org that kwin was updated to 6.3 after midnight on 20th but it didn't pull until now for me.

This was the last time we were using a certain VPS server for orchestrating the updates and moves and these took longer than expected. This caused version inconsistencies. To be prepared for such a case always make sure to have a backup or snapshot, with timeshift or other tool, and make sure to have pacman-static already installed.

We plan to start using a more powerfull VPS for this, this weekend.
