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 Ubuntu Desktop Bugs, 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] To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1968040/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
