# Three 1024x768 video projectors. ProjectorA is at the top, ProjectorB
# is below that, and ProjectorC is at the bottom. Each projector
# and is aligned on the left side. Note that the Absolute keyword
# is optional (and not supported by old versions of the server).

??? You can use the Above, Below, LeftOf, or RightOf keywords. This will cause the
top or left side of the screens to be aligned. For example:
# ProjectorB is to the right of ProjectorA. The tops of all
# projectors are aligned. Note that we don't need to know the
# resolution of the projectors - the the positions are
# calculated by the X server.
Screen 0 "ProjectorA" 0 0
Screen 1 "ProjectorB" RightOf "ProjectorA"
Screen 2 "ProjectorC" LeftOf "ProjectorA"
??? You can use the Relative keyword and specify a position relative to the upper-left
corner of another screen using X-Y pixel coordinates:
# ProjectorB is directly above ProjectorC on the left.
