Cannot log in to plasma desktop after crash, startplasma-x11 takes all the RAM

[rockingcat]

My Plasma desktop has crashed after launching some heavy AppImage with AppImageLauncher.

I had to force log out, but now I cannot log in anymore. Even after reboot.

I’m still able to log in with a new user created with useradd -m guest.

What happens (with an old user):

• I boot into sddm
• I type in the password and try to log in
• The desktop loading animation starts (splash screen)
• The loading animation freezes after a few seconds
• The process /usr/bin/startplasma-x11 starts utilizing 100% CPU and eventually takes up all the RAM (see the htop output) until the system becomes completely unresponsive (looks like a memory leak)

htop

I have a laptop with Intel CPU and Intel+Nvidia hybrid graphics.

• Manjaro release: 23.1.0
• Kernel: 6.6.7-1
• Plasma version: 5.27.10-1
• Display server: x11

What I have tried so far (didn’t help):

• Booting from a snapshot (I have / partition on btrfs, /home is on ext4)
• Checking the ext4 and btrfs filesystems from the backup system
• Remove the AppImage that caused the crash (also with ail-cli unintegrate)
• Booting from the older kernel (6.1) with fallback initramfs
• Reinstalling plasma-workspace and linux66-nvidia
• Booting with Intel graphics
• Full system update (from I think 2023-12-10 to 2023-12-15)
• Renaming Trolltech.conf and all plasma* files in ~/.config as was suggested here
  • Renaming the whole ~/.config
• Renaming ~/.cache and ~/.Xauthority as was suggested here
• Renaming kscreen, plasma, sddm in ~/.local/share/

The journalctl log of the last failed login might be helpful:

journalctl -b 0 -p4 --no-pager

These seem problematic.

Please check removing/disabling the pacnew checker one and also review xdg-user-dirs-update

Example mine;

$ systemctl --user status xdg-user-dirs-update.service 
○ xdg-user-dirs-update.service - Update XDG user dir configuration

Dec 18 16:35:10 HOST systemd[1114]: Finished Update XDG user dir configuration.

Another thought may be some odd foreign package replacing system base packages.
Check ‘foreign’ with

pacman -Qm

And probably unrelated but heres printing pacnews if any exist

pacdiff -o

PS.
You have no swap, so lockups are expected when you run out of RAM unless you have an OOM-killer or similar.
Setting up SWAP may mitigate the issue, and may be a good idea in general … though of course the runaway process is still a problem that needs to be resolved.

A wise man once suggested

Plasma desktop won't properly start anymore - high CPU load

I still say try the ‘configuration related’ steps: (I will augment them this time so that everything is backed up) cd ~/.config for j in plasma*; do mv -- "$j" "${j%}.bak"; done mv Trolltech.conf Trolltech.conf.bak kbuildsycoca5 --noincremental cd ~ Reboot. See if its ‘fixed’ … if so … start moving your configurations back one-by-one … find the culprit.

A random shot in the dark: did you have Plasma set to restore the previous session?

[varikonniemi]

having plasma set to restore a large appimage program that results in OOM could be a good way to get into this problem.

(unless plasma has some sane safeguards like: after unclean shutdown restore clean session)

printing pacnews if any exist
pacdiff -o

This returned nothing for me.

@cscs

You have no swap, so lockups are expected when you run out of RAM unless you have an OOM-killer or similar.
Setting up SWAP may mitigate the issue, and may be a good idea in general

Addressed, thanks for the tip! However, startplasma-x11 took all of that too, how nice

[cscs]

Make sure to try empty session and/or new user.
(if it does not affect the new user we know it is not a system-wide issue)

[rockingcat]

I will try it, thanks.
But first I’ll try your advice with the configs from another topic.

Plasma desktop won't properly start anymore - high CPU load

I still say try the ‘configuration related’ steps: (I will augment them this time so that everything is backed up) cd ~/.config for j in plasma*; do mv -- "$j" "${j%}.bak"; done mv Trolltech.conf Trolltech.conf.bak kbuildsycoca5 --noincremental cd ~ Reboot. See if its ‘fixed’ … if so … start moving your configurations back one-by-one … find the culprit.

Thanks @Takakage for pointing to that one.

[rockingcat]

@Takakage

A random shot in the dark: did you have Plasma set to restore the previous session?

Should not be the case. I mean, I don’t know where to check it except for graphical interface.

@varikonniemi

having plasma set to restore a large appimage program that results in OOM could be a good way to get into this problem.

I’ve also deleted the AppImage that caused the crash, so I’m not sure anymore what it loads my system with;)

@varikonniemi

unless plasma has some sane safeguards

Yeah, I very doubt it:)

[rockingcat]

Eem, running kbuildsycoca5 --noincremental resulted in a memory leak
Does it tell us something?

htop

[Yochanan]

@rockingcat

some heavy AppImage with AppImageLauncher.

What AppImage? All AppImageLauncher does is assist in integrating an AppImage into the system, so that’s not related.

What’s the output running the AppImage? It’s either in your ~/Downloads/ folder or ~/Applications/ if you chose to integrate it into the system with AppImageLauncher.

chmod +x name-of-AppImage.AppImage # if necessary, AppImageLauncher should have already done that
./name-of-AppImage.AppImage

[rockingcat]

I’ve already removed it completely from the system.
It was UltiMaker Cura app.

[Yochanan]

Ah, well. Problem solved then, eh?

[rockingcat]

Nope I still cannot log in to desktop, even after I removed the AppImage.
The process startplasma-x11 just freezes and takes up all the memory. The same happens when I run kbuildsycoca5 --noincremental from tty.

[cscs]

Yeah, but probably not on a new user ?

[aaaaaaaaaaaaaaa]

Had the same issue, but can confirm that the issue didn’t occur on other/new user accounts…

[rockingcat]

@cscs

Yeah, but probably not on a new user ?

Yes, with a new user I’m able to log in.

@aaaaaaaaaaaaaaa

Had the same issue, but can confirm that the issue didn’t occur on other/new user accounts…

Have you been able to solve the issue?

[brahma]

if renaming the cache and confgi folder didnt helped, try renaming these folders in: home/.local/share:
kscreen to kscreen.bak
plasma to plasma.bak
sddm to sddm.bak
reboot and see if it helped…

[cscs]

Can you also maybe check for any remnants of things in

ls ~/.{config/autostart,local/share/applications}

Tried renaming the .config, and .cache, and the folders you mentioned, but no luck unfortunately…

Yes, nothing seems unusual:

use startx instead of startplasma-x11 and post the output of the logs…
also you have optimus manager installed, and that could be the reason too… maybe uninstalling it + its configs, could help…
