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.</p>
<p>Overall I want to have the following structure:</p>
<ul class="remarkup-list">
<li class="remarkup-list-item">Platform receives configuration change request.</li>
<li class="remarkup-list-item">Platform implementation tries HW transformation (in Drm case via AMS test commit).<ul class="remarkup-list">
<li class="remarkup-list-item">If it fails optionally tries composited transformation.</li>
</ul></li>
<li class="remarkup-list-item">Afterwards the Platform will return configuration change request's succeeded or failed event and sets output device properties accordingly.</li>
</ul>
<p>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 <a href="https://phabricator.kde.org/T11459" style="background-color: #e7e7e7;
