<p>Still looking where these screen numbers come from...</p></div>

<p>working in Latte I had to understand how Plasma is working with screens, it might help you to understand it...</p>
<p>There is a <strong>plasma-workspace/app/screenpool.h</strong> class which is responsible for the ids you are mentioning.<br />
This class keeps a record the creates a table which is:<br />
ScreenName=id (e.g. 1,2,3,4, ... etc.)</p>
<p>That table can be found at <strong>~/.config/plasmashellrc</strong> e.g.:</p>
<div class="remarkup-code-block" style="margin: 12px 0;" data-code-lang="text" data-sigil="remarkup-code-block"><pre class="remarkup-code" style="font: 11px/15px "Menlo", "Consolas", "Monaco", monospace; padding: 12px; margin: 0; background: rgba(71, 87, 120, 0.08);">[ScreenConnectors]
0=HDMI-1
1=eDP-1
2=eDP-1-unknown
3=eDP-1-1
4=:0.0
5=Screen26
6=Screen36</pre></div>
<p>screenpool class is responsible to maintain that table and also to inform applets, containments, coronas etc for<br />
associations between ids and screens</p>
<p>the Corona class has a <strong>screenForContainment()</strong> function that helps at that communication between applets<->screens</p>
<p>screen() and lastScreen() : functions usually return the id of the screen based on ScreenConnectors</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R120 Plasma Workspace</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D10344">https://phabricator.kde.org/D10344</a></div></div><br /><div><strong>To: </strong>hoffmannrobert, Plasma<br /><strong>Cc: </strong>mvourlakos, mart, ngraham, plasma-devel, ragreen, Pitel, ZrenBot, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol<br /></div>
