Default Re: Triple-Head Setup without Xinerama?

Hi all,

just to let you know: the setup described above works with Matrox
TripleHead2Go! The TH2G box has both, a DVI input and DVI outputs
(in contrast to the DualHead2Go box, which has a VGA input, only)
and can be programmed to operate at 3200x1200 for two LCDs (DualHead
mode).

However, you need to add the mode "1600x1200@60" to the "mode list"
stored inside the TH2G using the supplied setup tool on a windows computer
(a windows installation on VMware will also do it). This needs to be done
only once.

Games are now even faster than with two video cards (because of no
Xinerama overhead, i guess) and moving a window to the third LCD
doesn't cause annoying redraw events any more. Also, a small but
annoying miss-drawing in X-Plane has gone.

Compiz should also work now at 4800x1200, but i didn't yet tried it out.
