Description Loïc Grobol 2017-07-11 15:43:29 UTC
Plasma doesn't start on session opening and leaves me with a black screen. Everything else works, though, so I'm able to access KRunner and yakuake.

When I run plasmashell from yakuake I get

    $ plasmashell

While doing this, the wallpaper with the home and trash folder briefly appears, but nothing is clickable and everything quickly goes back to black. No panel appeared.

What I have already tried
  - deleting (moving) .cache/
  - deleting .config/
  - reinstalling plasma-desktop-data
  - tried xserver-xorg-video-amdgpu, xserver-xorg-video-ati and neither

None of which made any noticeable changes.

So, what can I do now ?
Comment 1 Kai Uwe Broulik 2017-07-11 15:49:29 UTC
Can you run plasmashell through gdb (gdb plasmashell and then on its console type run), once it crashed do thread apply all bt and paste here.

Thanks! Seems to crash in the print manager applet.

As a workaround you can try removing "org.kde.plasma.printmanager" from all occurrences of "extraItems" in your ~/.config/plasma-org.kde.plasma.desktop-appletsrc

Indeed

Strange and probably unrelated, but I tried that and starting plasmashell still doesn't work and it puts these references back in the file. (there were no plasmashell instance running when I made the change)
Comment 6 Loïc Grobol 2017-07-11 16:36:09 UTC
Ok, what did the trick was to completely remove print-manager.
