I have a laptop that I use either on a dock or not connected to anything. When it's not on the dock, everything works OK.

When on dock, plasma loads a long time and starts without wallpaper and panel. I have to run Konsole, kill plasmasession and start it manually. Then, everything works OK.

Code: Select all

may@ThinkMay:~$ cp .xsession-errors errorlog
may@ThinkMay:~$ killall -9 plasmashell
may@ThinkMay:~$ nohup plasmashell &
[1] 2583
may@ThinkMay:~$ nohup: ignoring input and appending output to 'nohup.out'

(then everything's OK)

I'm looking at the log file but there're so many warnings and errors that I cannot find my way around them.
Can you please help me diagnose what goes wrong so I can fix it (i.e. make it start without having to manually kill and restart session)?

Here's the xsession-errors:
