Hello.

I seem to be hitting the same bug and I have attached the drm_info output while the screen is stuck in the off state.

I see the the same Failed to post KMS update: drmModeAtomicCommit: Invalid argument and Page flip discarded: drmModeAtomicCommit: Invalid argument in my logs while the the monitor is stuck. It gets stuck when I turn my monitor off from inactivity or the monitor turns itself off after locking the computer.

Putting MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 in /etc/environment fixed it for me.

Rarely the screen also flickers at random moment, turns dark for a second, and then turns back on. When I checked the logs after it, I see the drmModeAtomicCommit: Invalid argument lines again.

I have Ubuntu 22.04 with an external monitor Single display setup. Also Intel.
