The "sync crtc" is the crtc used to drive the display timing of a
drawable under DRI2 and DRI3/Present. If a drawable intersects
multiple video outputs, then normally the crtc is chosen which has
the largest intersection area with the drawable.
If multiple outputs / crtc's have exacty the same intersection
area then the crtc chosen was simply the first one with maximum
intersection. Iow. the choice was random, depending on plugging
order of displays.
This adds the ability to choose a preferred output in such a tie
situation. The RandR output marked as "primary output" is chosen
on such a tie.
This new behaviour and its implementation is consistent with other
video ddx drivers. See amdgpu-ddx, ati-ddx and nouveau-ddx for
reference. This commit is a straightforward port from amdgpu-ddx.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server
