D24112: [platforms/drm] Disable setting 90° transformation s

romangg added a comment.


  Thanks for looking into this. But I don't think there is a (good) solution possible without some principle changes. For example wayland output device transformation is set in the Drm backend but should be set on AbstractWaylandOutput level.
  
  Overall I want to have the following structure:
  
  - Platform receives configuration change request.
  - Platform implementation tries HW transformation (in Drm case via AMS test commit).
    - If it fails optionally tries composited transformation.
  - Afterwards the Platform will return configuration change request's succeeded or failed event and sets output device properties accordingly.
  
  That's something I had in the back of my mind already for some time but since it was not possible for 5.17 anymore I worked on other tasks for now. Will be part of T11459 <https://phabricator.kde.org/T11459>.
