OK, the final thing to try is to replace the above environment variable with:
MUTTER_DEBUG=kms then reboot, reproduce the hang in a Wayland session, reboot again and run: journalctl -b-1 > kmsdebug.txt and attach the resulting text file here. That will tell us if gnome-shell is sending the right instructions to the kernel to sleep/wake the screen. If it is then this is no longer a gnome-shell/mutter bug. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1977977 Title: Blanked screen doesn't wake up after locking To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1977977/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
