<p>It is possible for one of the DMX "backend displays" to actually be smaller than the dimensions of the backend X server. Therefore, it is possible for more than one of the DMX "backend displays" to be physically located on the same backend X server. This situation must be detected so that cursor motion can be handled in an expected fashion.</p>

<div class="textblock"><p>It is possible for one of the DMX "backend displays" to actually be smaller than the dimensions of the backend X server. Therefore, it is possible for more than one of the DMX "backend displays" to be physically located on the same backend X server. This situation must be detected so that cursor motion can be handled in an expected fashion.</p>
58
70
<p>We could analyze the names used for the DMX "backend displays" (e.g., the names passed to the -display command-line parameter), but there are many possible names for a single X display, and failing to detect sameness leads to very unexpected results. Therefore, whenever the DMX server opens a window on a backend X server, a property value is queried and set on that backend to detect when another window is already open on that server.</p>
59
71
<p>Further, it is possible that two different DMX server instantiations both have windows on the same physical backend X server. This case is also detected so that pointer input is not taken from that particular backend X server.</p>
60
72
<p>The routines in this file handle the property management. </p>
