Re: rebooting after upgrade alway a complete mess
Since starting "mpv" after reboot, again, broke kwin/plasmashell, who knows...
I thought of:
Settings>Compositor Settings for Desktop Effects
untick "allow application to block compositing"
Then "apply"
=> kwin/plasmashell crash!
Then logout: no way to have cursor/mouse pointer with sddm
Even after several tty/root/ systemctl restart sddm
I had to reboot the computer...
Something is rotten in the kingdom of Denmark!
I don't know what's coming next, but I thought it was a relevant piece of
information.
