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 :
