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. ** Attachment added: "drm_info.txt" https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1968040/+attachment/5705009/+files/drm_info.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1968040 Title: [i915] Blanked screen doesn't wake up after locking [drmModeAtomicCommit: Argument invalide] [drmModeAtomicCommit: Invalid argument] Status in GNOME Shell: New Status in Mutter: New Status in linux package in Ubuntu: Confirmed Status in linux-hwe-5.19 package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: [ Workaround ] Add to /etc/environment (in Ubuntu 22.04): MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 or in Ubuntu 22.10 and later: MUTTER_DEBUG_FORCE_KMS_MODE=simple and then reboot.

The only reliable workaround I've found is to press Ctrl+Alt+F1. That's on a fully up-to-date jammy, my hardware is an Intel NUC with a single Samsung monitor connected with a standard HDMI cable. This is a regression that started happening yesterday (2022-04-05) if I can remember correctly (I do apply pending updates at least once daily).
