Had problems with google meet in chromium, so rebooted.

Stuck after SDDM login because Plasmashell & org_kde_powerdevil crashes on boot.

Tried downgrading glibc, since libc was mentioned multiple times in the stack trace, but no luck.

did you do partial upgrade or full -Syu?

mental harness Jan 19, 2026, 2:56 PM

#

quaint moss did you do partial upgrade or full -Syu?

I always do full -Syu, never partial.

#

But might be that I didn't reboot last 1-2 times, I use sleep often with the laptop.

mental harness But might be that I didn't reboot last 1-2 times, I use sleep often with the lap...

thats probably not related

#

uhh

#

this is probably some sort of library incompatibility

#

which is not supposed to happen because you did -Syu

#

idk

mental harness Jan 19, 2026, 3:03 PM

And it is also up to date.

could there have been corrupted packages?
