KDE rocky linux v10 crashing

Rocky Linux Help & Support

Dear Rocky Linux-ers :slight_smile:

Sometimes Rocky Linux is unable to fully load KDE system settings (crashes) & i can’t see power option to reboot, just shows - LOCK, LOG OUT & Switch User. I have to use terminal, but that isn’t viable to less technical users.

Is there a way to refresh the KDE desktop environment without reinstalling the OS? The desktop is unstable, have tested it on various hardware - quite intermittent.

Sometimes when you shutdown, it just reboots the device or doesn’t shutdown via the KDE-menu.

Have tried kquitapp6 plasmashell & kstart plasmashell, but it just hangs.

I think this only happens with v10 rocky linux KDE version.

Yes but it will require you going through your home directory and finding any of the config directories relating to KDE and deleting them. At least I’m not aware of any easier way of doing it, than that.

Thanks, so will deleting all the related config reset the desktop please? I don’t know why KDE is problematic on Rocky unlike Gnome. KDE on Arch is very stable …

Will leave it as i don’t want to reinstall KDE Rocky Linux from scratch ; there has to be a better path :slight_smile:

Rocky by default doesn’t come with KDE - KDE comes from EPEL and EPEL are responsible for it’s stability or instability. It has nothing to do with the Rocky team.

And yes, deleting the config directories will reset KDE desktop so that you have to reconfigure it again.

One possible way to figure out what/where some of the config is to create a new user, log in as it, and out. Then look at the home directory. Naturally, there will be other things (Documents, Downloads) created too, and some config files are probably not created unless one does particular customizations.

Then again, does KDE document where they put user-specific config?

Usually find should help with that, eg:

find ~ -iname *kde*

But a google search also does show up results, like:

the latter being somewhat more verbose than my command.

Otherwise, a more simple approach is:

  1. Backup your files like /home/username/{Documents, Downloads, Music, Pictures, Videos, etc}
  2. Delete the entire contents of /home/username including all hidden files - or just delete the home directory and recreate it.
  3. Login to the system and restore your files from point 1.

That will ensure pretty much every file possible related to config will no longer exist, not just for KDE, but for every app you used.

Thanks, For some reason, i can’t see the config files even on hidden, can see .profile & .kconfig, so i will try below

  1. So if i try rm -rfv /home/testusr*
  2. Or best to just delete the user & re-create the user again? (userdel -r testusr)
  3. Will i be able to create the same username as the deleted one?

Tried it & deleted the user & created it again, KDE was still crashing …

Found the config files, will see how it goes?

There has to be a reset for KDE desktop, very unstable on RL v10.

As I said, nothing to do with the Rocky team. If you have instability issues, report it to EPEL.

I know thanks, but RL & KDE were bundled, i didn’t add the plasmashell separately. Just commenting that the previous ver seemed more stable.

Hopefully the cinnamon version of v10 would be ready soon to test…

Appreciate the support @iwalker :folded_hands:

el10 does not include Xorg. Hence KDE must run with Wayland.
el9 has Xorg, so there KDE can use X11 (or Wayland).
If KDE has been using X11, then support for Wayland is new to it, which could explain some issues.

Thanks for this remark @jlehtone , quite logical
