Default Re: TwinView - Triple screen/multiple gfx cards support?

However, applying TwinView causes undesired Xinerama information.

I have created a quick&dirty patch for libXinerama to overcome
that problem. For details, please refere to

I guess Windows doesn't cause refresh events for moving windows ...

IMHO, a compositing window manager for Linux (such as beryl) should
basically also overcome that issue, but this feature is not yet available
for Xinerama configurations :-(

I'm using two 7800GTX cards in an SLI capable mainboard, but configured
as a triple-head setup (since more than a year). The SLI bridge is applied
to the video cards so that i can switch to SLI "on the fly", if necessary.
