Recently upgraded to Ubuntu 22.04, and it seems like the power-saving feature in Gnome 42 does not actually turn off the screen(s) after X minutes, but just blanks them. When I manually run `xset dpms force off`, they do properly turn off and go to powersave mode.

1) Description: Ubuntu 22.04 LTS
Release: 22.04
2) gnome-settings- daemon:
Installed: 42.1-1ubuntu2
Candidate: 42.1-1ubuntu2
3) In Settings -> Power -> Screen Blank, set the inactivity period to 5 minutes. After 5 minutes, the screens should turn off.
4) Screens go black, but remain active and consume (too much) power.
