KDE hangs on login after resume

Hi,

After I login from sddm KDE starts but hangs ( pointer arrow visible, but no longer moving.). I then need to press a hard ' off'  on the laptop.

I think this only ( mainly?) happens after resume from sleep or hibernate, but i am not sure.
After hard reset, I can login to KDE as usual.

Journalctl:  journalctl -b -1  gives:

I do not see any specific signs of error in this log ( but I am also not sure what to look for).

Thanks for any hints,

Alex.

Re: KDE hangs on login after resume

Don't hard reset. Generally speaking after a new KDE release new shaders need to be built and compiled and depending on your GPU  it might take a while to compile them, so instead of hard rebooting what happens if you just wait a bit? And in any case instead of hard resetting you're likely able to switch tty and reboot instead. Which is also more likely to retain logs. Or if you can't switch TTY https://wiki.archlinux.org/title/Keyboa … el_(SysRq) ought to work after enabling it and is the better/safer and saner approach to retain the journal.
