The MUTTER_DEBUG_ENABLE_ATOMIC_KMS worked for me as well, thank you!

Title:
  Display powersave only blanks, but does not turn off

Status in gnome-settings-daemon package in Ubuntu:
  Confirmed
Status in mutter package in Ubuntu:
  Confirmed

Bug description:
  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.
