I updated my desktop PC yesterday, (# pacman -Syu) only to discover nothing would launch after login. I use KDE 5 on Arch Linux. Whenever I clicked the ‘K’ application menu, I received a message indicating that the org.plasma.private.kicker module was not installed.
What the heck is that?
I worked around it for a day (yesterday, 2017-01-23) by holding the shift key and typing the first letter of the application I wanted to run. [SHIFT+F] to bring up the run command and then finishing with ‘irefox’ would get my web browser running.
That got me through the day yesterday, but today, I decided to take a few minutes and try to resolve the issue. Since I didn’t know what the problem was, I simply decided to reinstall xorg-service and the plasma group.
# pacman -S xorg-server plasma
Did the trick, by reinstalling the packages from my cache. I’m now a happy desktop GUI using camper. 😀
