Hi,
Since this morning, after loging in on a Plasma KDE session, I can
first see the desktop then only a black screen with only the mouse
available, nothing else.
Ctrl+Alt+Suppr, brings the log out screen so I can log out.
I can also switch to a text terminal with Ctrl+Alt+F2. That's all.
On the fedora users mailing list, we identified that it is due to
plasmashell crash.
If none of the crash handlers catch this (like abrt or drkonqi), you can try
running plasmashell under gdb to get a backtrace. One way, use krunner
(ALT-F2) to launch konsole, then run:
gdb /usr/bin/plasmashell
...
(gdb) run
... wait for crash...
(gdb) thread apply all backtrace
and post the result (ideally, you may need to install some -debuginfo to get
a more useful backtrace).
