Bug ID: 417672
Summary: PlasmaShell won't start
Target Milestone: 1.0
After completing all the available updates yesterday I noticed that suddenly
some of the applications, such as krunner wouldn't work anymore and others
could not be terminated anymore. As the shutdown app did not work either, I had
to use the shutdown terminal command to terminate Kubuntu. When I tried to
start up the system, the booting procedure stopped bootsplash and did not go on
into the login screen. Watching the booting procedure in the command line mode
does not show any errors. After the line saying something like
...user-session... the screen is cleared. Entering the command line mode again,
I can login as usual. However, if I try to strart PlasmaShell, I get the
qt.qpa.xcb: could not connect to display
qt.qta.plugin: could not load the Qt platform plugin "xcb" in "" even though it
This application failed to start because not Qt platform plugin could be
initialized. reinstalling the app may fix this problem
Available platform plugins are: wayland-org.kde.kwin.qpa, eglfs, ...
fish: 'kstart5 plasmashell' terminated by signal SIGABRT (Abbruch)
Reinstalling xcb did not fix anything.
STEPS TO REPRODUCE
1. Start computer
KDE Frameworks 5.67.0
Using startx I get a very basic gnome desktop. starting plasmashell from there
works but most of the destop functions are not working. Also, the display
configuration in the system settings is not available.
