<p>We go now through AbstractWaylandOutput virtual functions to enable and<br />
disable outputs.</p>
<p>Dpms changes and enablement switches use separate code paths at start in the<br />
Drm backend code since they are similar but not the directly same. Common code<br />
is shared though, functions are renamed accordingly.</p>
<p>Asserts have been put in place to better understand and check the control<br />
flow. A seemingly unnecessary call to DrmOutput::pageFlipped on reactivation<br />
after Vt switch has been removed to allow for that.</p>
<p>In future patches we need to look additionally at the legacy mode switching<br />
code path which was and is still not working and better handling of the<br />
current monitor Dpms state. For example a monitor being switched off is not<br />
properly acted on and the workspace still expanded.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>With one and two monitors:</p>
