Actually the bug just happened to me and now I can see "drmModeAtomicCommit: Invalid argument" in my logs now. So it turns out I am experiencing this bug.
I will try the work around posted at the top of the first post: [ 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. -- 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: 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
