Ubuntu 21.10 - "Failed to grab modeset ownership" with 495.44

Graphics / Linux Linux
40

Not a solution, but a workaround.
After boot, when all I get is a black screen:

  1. Switch to console (Ctrl-Alt-F1) and login as root
  2. init 3 # shut down X
  3. init 5 # restart X
  4. Switch back to graphical login (Ctrl-Alt-F7)

Works for me on openSUSE Tumbleweed.
