Title:
  Desktop cannot resume after suspend: screen not detected

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hardware:

  - Desktop PC (Intel i5 4th gen)
  - GPU: AMD RX580
  - Ubuntu 22.04 with kernel HWE 6.2

  Steps to reproduce:

  1. Start the device
  2. Suspend
  3. Resume by pressing a key on the keyboard

  Expected results:

  The screen lights up, showing the screen to put my password to resume
  the session.

  Actual result:

  The screen OSD displays a "No Signal" message before turning off.
  Nothing seems to happen when I press keyboard keys or move the mouse.

  Switching to a TTY by pressing Ctrl+Alt+F3 works: I can login and see
  the logs (that's how I filed this bug).

  Switching back to graphics session (Ctrl+Alt+F2) does't work: it shows
  the cursor and nothing else (black screen).

  Switching to login screen (Ctrl+Alt+F1) works: I can see the list of
  users, select on and enter my password... but then I'm back to the
  same black screen with the mouse cursor.

  This is not a regression, as the same problem happened already with
  the previous point release (I believe it was Linux kernel 5.15).
