I am facing the same issue since upgrading from 20.04 to 22.04.

I have a Lenovo ThinkPad X1 Extreme Gen 3 with an external monitor (Dell P2720DC) connected via USB-C displayport that used to turn off completely but now only blanks with the backlight remaining on.

Display server: X11
Display driver: Nvidia 510.85.02

`xset dpms force off` turns off monitor correctly
gjs is already installed

Any help with debugging this would be useful since I don't see any issues in journalctl

I still need to test if Nvidia Prime profile has any effect (performance vs on-demand) or if same occurs under Wayland.
