themselves and WaylandServer announces the Outputs to Wayland.</p>
<p>So far this was static: at startup it got announced once to Wayland<br />
and any changes were not catched.</p>
<p>This change makes WaylandServer listen to changes to the Screens and<br />
sync them to Wayland.</p>
<p>Unfortunately KWin's internal Screen information is not sufficient to<br />
properly synchronize this to Wayland and also Wayland by not supporting<br />
adding/removing modes does not help.</p>
<p>Thus the solution implemented here is to add new outputs reflecting the<br />
changes and then removing the old ones. This creates situations with more<br />
outputs being present than actually there, but prevents that there are<br />
no outputs at all.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>Auto test added which verifies this for the virtual platform</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>rKWIN KWin</div></div></div><br /><div><strong>BRANCH</strong><div><div>announce-output-changes-to-wayland</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D2233" rel="noreferrer">https://phabricator.kde.org/D2233</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>autotests/integration/CMakeLists.txt<br />
