Has anyone else experienced this? Fairly frequently I find that kwin
on F25 is not starting on login, there are no window decorations (e.g.
title bar) and all new windows start at top left with no apparent way
to move them. The solution seems to be to start a console and run
This morning however I didn't even have a desktop, just a cursor and
an otherwise black screen. What was working was that typing brought up
the command bar at the top of the screen, so I was able to start
konsole. "kstart kwin" and "kstart kwin --replace" didn't seem to
achieve anything (though maybe I could have waited longer), eventually
tried "kstart plasmashell" and things seemed to run again.
This is the nouveau driver. I've had problems on F25 with getting
stuck at the splash screen ("K") after login, but adding nomodeset to
the kernel line in grub seemed to alleviate that, and I was using
nomodeset this morning.
