I encouter this as well a few times recently, seems to be related to
some of the latest updates. For some reason "plasmashell" seems to
crash
sometimes. This can be pretty painful if krunner is crashed as well
(and
feels like always...). So try press "ALT+F2" and run "kquitapp
plasmashell & plasmashall" or try to get into a console and launch the
command there. After a few seconds the desktop shall be there as
normal,
even tho these crashs are extremly nasty...
[SNIP]
Florian's description of "black scrren and cursor" sounds like text
mode, not an x-windows dispaly.
That being said, I don't get that problem, and I never put my system
to the sleep/hibernate state - but I get what sounds like something
simlar in principle at least once per day and often as many as 4-6
times in a day when I unlock the screen.
To me the worst part is when the screen is unlocked and this happens,
there is (of course) no panel, and all I can see is the black screen
with whatever windows were open when I locked the screen. Any windows
which were iconized when I locked it are impossible to get to.
ASIDE: +I don't know whether it's related or not, but frequently
(possibly always, although I don't always keep top running somewhere
to determine whether this is the case) before this happens I'll
notice a krunner process which is using extremely large of amounts
cpu (>100% for more than a few seconds). That causes me to wonder
whether something in krunner gets caught in a loop.
Sometimes I use the same sequence as Florian ("kquitapp plasmashell &
plasmashall") but it doesn't always work.
FWIW I also get FREQUENT error message boxes telling me that this
or that kde component has crashed. Sometimes I believe they have;
however, more often a search of /var/log and/or /var/account/pacct
does not record the crash and I suspect some other glitch in kde5 is
causing a false error message.
I've been using the KDE desktop on virtually every machine where I
have a login for longer than I can remember, and the many glitches in
kde5 make me long for the stability, usefulness, and configurability
of kde4.
