Description Wyatt Childers 2021-01-24 22:05:23 UTC

SUMMARY
Using an nvidia wayland session, logging out, then logging back in from sddm results in a broken graphics stack.

STEPS TO REPRODUCE
1. Start a nvidia wayland session
2. Logout
3. Start a new nvidia wayland session

OBSERVED RESULT
The system appears on what I believe to be plymouth boot screen (in my case the Fedora + Gigabyte boot screen). 

Attempting to leave via a tty to investigate, fails; a reboot via the power button is required.

EXPECTED RESULT
The login works as it normally would.

ADDITIONAL INFORMATION
This doesn't seem to happen every time.

The Nvidia driver had some huge changes and how it interacts with KWin. Please try again and file new bugs as appropriate thank you!
