[Solved] KDE applications gone after update

Hello,

yesterday I did a system upgrade with pacman -Syu and since then I've experienced problems with my KDE.

At first, I only saw a black screen after logging in and and my screens were duplicated instead of extended, I fixed this by adding the nvidia_drm.modeset=1 kernel parameter to my grub configuration as mentioned here: https://bbs.archlinux.org/viewtopic.php?id=293626

Now I can login and it looks mostly normal, except for the fact that all applications seem to have disappeared. What I pinned to my task bar now gets me errors that the path doesn't exist and the start menu is completely empty. Some applications like dolphin and chromium I can still launch with alt-f2, but when I right click on a file and select open with... the list is also completely empty. Google chrome apparently has uninstalled completely. I can select Wayland or X11 with my desktop manager when logging in but this makes no difference.

My search for these specific issues was not very helpful so far, so I'd appreciate any advice, thank you.

I still need help with this.

In addition, the problem seems to only affect my user account. Another account on the same machine is fine.

I'd rather not completely reset my kde configuration though if that can be avoided.

Did you compare the environment variables?

The same command from above yields this in the other account:

XDG_CONFIG_DIRS=/home/<name>/.config/kdedefaults:/etc/xdg
XDG_SESSION_PATH=/org/freedesktop/DisplayManager/Session3
XDG_MENU_PREFIX=plasma-
XDG_SEAT=seat0
XDG_SESSION_DESKTOP=KDE
XDG_SESSION_TYPE=x11
XDG_CURRENT_DESKTOP=KDE
XDG_SEAT_PATH=/org/freedesktop/DisplayManager/Seat0
KDE_SESSION_UID=1001
XDG_SESSION_CLASS=user
KDE_SESSION_VERSION=6
XDG_VTNR=2
XDG_SESSION_ID=5
XDG_RUNTIME_DIR=/run/user/1001
KDE_FULL_SESSION=true
KDE_APPLICATIONS_AS_SCOPE=1

I don't see any meaningful differences between the two...

Re: [Solved] KDE applications gone after update

gets me errors that the path doesn't exist

What exact error on what exact path?

Wild guess, run https://man.archlinux.org/man/extra/kse … coca6.8.en --noincremental

Thank you seth and anyone else who tried to help.

I ran the command kbuildsycoca6 --noincremental and instantly my icons reappeared and my start menu is populated again. As far as I can tell everything is back to normal now.

For the record, the error I got when trying to run applications I had pinned to my task bar was "unknown application folder" as a plasma notification, for example when trying to launch dolphin that way.

Thanks again and best regards
