Well I did not forget. The joke is, I did not encounter the « bug » since.
Maybe some regular update solved the thing ? Mutter, mesa, gnome-shell, gdm… there had been a few updates for them since, so who knows ? -- 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/1983175 Title: In Wayland, can't wake up monitor after it has gone black Status in mutter package in Ubuntu: Incomplete Bug description: Hi, sorry I don't know if it's about GDM or else. Ubuntu 22.04.1 LTS jammy Linux 5.15.0-41-generic x86_64 x86_64 ubuntu / wayland installed DE's are : ubuntu.desktop ubuntu-xorg.desktop My system is set to turn screen black after some minutes. And after some other minutes later, it locks the screen → no sleep nor hibernate involved ( even if sleep and hibernate are ok on that machine. ) On Xorg, after screen's gone black, any mouse or keyboard solicitation fires up again the screen, as expected. On Wayland, after screen's gone black, any mouse or keyboard solicitation just does nothing, screen stays black. BUT keyboard is not turned off : only thing that works for « waking up » the screen is key-combo [ ctrl ] + [ alt ] + [ F1 ] If of any interest : django@ASGARD:~$ sudo lshw -c video [sudo] Mot de passe de django : *-display description: VGA compatible controller produit: Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller fabricant: Intel Corporation identifiant matériel: 2 information bus: pci@0000:00:02.0 nom logique: /dev/fb0 version: 06 bits: 64 bits horloge: 33MHz fonctionnalités: msi pm vga_controller bus_master cap_list rom fb configuration : depth=32 driver=i915 latency=0 resolution=1920,1080 ressources : irq:33 mémoire:f7800000-f7bfffff mémoire:e0000000-efffffff portE/S:f000(taille=64) mémoire:c0000-dffff django@ASGARD:~$ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1983175/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
