Hi Aleix,

Maybe my post wasn't clear, this is for multi-screen/multi-monitor setup,
so for example I need to set the dock to screen 1 or screen 2 etc.

I've already used layer-shell to set the dock's anchor, strut, and
layer, but it doesn't seem to support setting screen/monitor?

Thanks,
Viet

Given you&#39;re asking about a dock in the KWin list, you should be using<=

layer-shell. It does allow setting the output when placing it:<br>

As C++ API you can use layer-shell-qt:<br>

&gt; Hi,<br>
&gt;<br>
&gt; On Wayland, is there any way for third-party docks to set the screen w=
here the dock resides?<br>
&gt;<br>
&gt; I&#39;ve looked through the Wayland protocol list but did not find any=
thing relevant.<br>
&gt;<br>
&gt; Thanks a lot,<br>
