    [Linux / AMDGPU] monitor power cycling disables monitor (and borks screen layout).


      Whenever I turn one of my monitors off it is removed from my screen layout.

      When I turn it back on it is disabled on the display configuration screen.

      Disabling DPMS has no effect.

      Initially: DisplayPort-2 connected 1200x1920+0+0 left

      Powered off: DisplayPort-2 disconnected

      Powered back on: DisplayPort-2 connected



      Is there something I can do to fix this?

      I would like to keep my display configuration locked and have my system totally ignore monitor power status.


      Is this due to KMS. Can I disable KMS in AMDGPU?
