[ Test Plan ] Try to log into gnome-shell. Verify there is a picture on the screen. [ Where problems could occur ] The offending code change relates to Intel-specific chip IDs so the change is limited to Intel systems. Although affected Intel systems worked perfectly before the change so we don't expect any problems in reverting the change. In theory the worst case is limited to more problems like that described in Impact above. [ Workarounds ] Add MUTTER_DEBUG_USE_KMS_MODIFIERS=0 to /etc/environment or upgrade to a newer kernel: sudo apt install linux-generic-hwe-22.04 [ Other Info ] The log messages relating to this bug are: iul 11 19:00:11 MY-PC gnome-shell[1040]: Failed to lock front buffer on /dev/dri/card0: drmModeAddFB2WithModifiers failed: Invalid argument iul 11 19:00:11 MY-PC gnome-shell[1040]: Failed to lock front buffer on /dev/dri/card0: drmModeAddFB2WithModifiers failed: Invalid argument iul 11 19:00:11 MY-PC gnome-shell[1040]: Failed to lock front buffer on /dev/dri/card0: drmModeAddFB2WithModifiers failed: Invalid argument iul 11 19:00:11 MY-PC gnome-shell[1040]: Failed to lock front buffer on /dev/dri/card0: drmModeAddFB2WithModifiers failed: Invalid argument ... For kinetic: The bug never existed in mutter 43.0 (it was introduced in 43.2) and was already fixed in the kernel anyway. For lunar and later: The bug was already fixed in the kernel. You would only ever encounter it in theory if you downgrade the kernel.
