I have a problem like in this question: After booting I come into a desktop w/o taskbar and where the desktop is not reacting to right click. Most of the times krunner works, so I can start programs (Ctrl+Alt+T opens a terminal as well, moving the cursor to the top left corner shows all current windows, I can switch between virtual desktops by shortcuts). I deleted .config/plasma*
, .kde4/
and even created a new user, but nothing seems to help with the problem. When logging in, KDE is loading, but the splash screen hangs for several seconds at the end, before showing the desktop. Oddly, there is an artefact of the taskbar on the lower left screen corner, which is about 1px wide and has the height of the taskbar (and also the slight "glare" around it).
I tried restarting it manually with kstart plasma-shell
which gives me
kstart(1597) main: Omitting both --window and --windowclass arguments is not recommended
. Running kquitapp plasma-shell
beforehand just hangs.
I have this issue since updating from KDE 4 -> 5. A few times it resolved itself or I could resolve it by deleting above mentioned folders, but mostly it didn't help. When it is working, the issue reappears either for example when I take out/plug in my laptop to the docking station by crashing plasma-shell
(it asks me to report a but then, which it declines because of too few information) and clicking restart doesn't work.
Any hints about how to resolve this or where to look at (journalctl
gives me no errors) would be greatly appreciated. I'm running Arch Linux on a Lenovo T410 (Intel HD graphics).
EDIT
Here the console output from one of the few times where I could restart plasmashell from the konsole (got the background image that way, but still no taskbar). The last lines are repeated on and on (a few of them per second)
