SUMMARY
When trying to login to KDE Plasma desktop from the graphical login screen, it
crashes See attached core dump ((kwin_wayland). On the same laptop, selecting
KDE-X11 Desktop or Gnome Wayland works fine, so it is only KDE Plasma that no
longer works/crashes. I did not have this problem before Jan. 28,2022.
STEPS TO REPRODUCE
1. I rebooted my laptop (Dell Latitude 5590 running Fedora Core 34) after a
"dnf update".
2. At the graphical login screen, I select KDE Plasma desktop.
3. I get a black screen, nothing happens.
OBSERVED RESULT
I get a black screen.
EXPECTED RESULT
I should be getting my KDE Plasma Desktop.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora Core 34
KDE Plasma Version: plasmashell 5.22.5
KDE Frameworks Version: 5.85.0
Qt Version: 5.15.2
All these were installed via the "dnf" command and the Fedora "update" rpm
channel.
ADDITIONAL INFORMATION
Today I rebooted my laptop (Dell Latitude 5590 running Fedora Core 34) after a
"dnf update".
At the graphical login screen, I selected KDE Plasma desktop, and put in my
username and password, hit enter, then I get a black screen, nothing happens. I
waited several minutes, still no desktop is shown. I have never had this
problem before, KDE Plasma Desktop has worked very well for me previously.
Prior to today's reboot, I did "dnf update" and rebooted the laptop on Jan 28,
2022 and everything worked fine on Jan 28. So it seems there is some rpm
package that got installed AFTER Jan 28, 2022 that is causing this problem.
For testing: I rebooted the laptop and at the graphical login screen I selected
KDE-X11 desktop, it brings up the KDE-X11 desktop just fine. I also tried the
GNOME Desktop and it also works fine, after that I tried the KDE Plasma desktop
again but it still crashes. See attached core dump.
