multi monitor/multi card status

[Matt Thrailkill]

I spent a lot of time a few months ago trying to get 6 video outputs
from multiple Nvidia cards with the Composite extension also.  The
closest I got was using Xgl, but I found a software bug there that
would screw up some of the drawing.

I ended up breaking down and buying two Matrox Triplehead2Go boxes and
using a single videocard to drive 6 displays instead.

I will be glad when eventually X.org has this functionality.  It is a
long time coming.
