logs.txt
Application: plasmashell (5.18.6)
Qt Version: 5.12.7
Frameworks Version: 5.76.0
Operating System: Linux 5.3.18-59.37-default x86_64
Windowing system: X11
Distribution: openSUSE Leap 15.3
-- Information about the crash:
- What I was doing when the application crashed:
I just login in SDDM (automatic login without passwod), for some seconds I see
splash screen with more than half percentage of progress bar passed, finally
either black screen appears (most often) or sometimes I press
Ctrl+Alt+Backspace to restart sessions and after that I can load full Plasma
desktop.
- Unusual behavior I noticed:
No Kwin window decorations. Even if I see black screen, most often I can press
Alt+F2, and in this way open program (e.g. konsole).
I use X (xcb), not Wayland.
In logs I can see:
kglobalaccel5[1489]: qt.qpa.xcb: could not connect to display :0
I also see:
systemd[1]: No hostname configured.
systemd[1]: Set hostname to <localhost>.
NetworkManager[969]: <info> [1641065313.0076] policy: set-hostname: set
hostname to 'localhost.localdomain' (Error reverse-resolving “10.0.2.15”: Name
or service not known)
systemd-hostnamed[981]: Changed hostname to 'localhost.localdomain'
I doubt where host name change helps...
This is LiveDVD system.
The crash can be reproduced sometimes.
