:0.0 is an NVidia GeForce2 card, and using the NVidia magic drivers, I get fairly nice OpenGL performance. :0.1 is a cheap card (an S3 Trio3D, I think); I have no idea if I actually have 3D acceleration on that or not. If important goals are "have two heads" and "play TuxRacer", this is perfectly adequate; if you really absolutely want accelerated OpenGL support on both displays, you might need to do something a little harder or expensive; I suggest the second video card approach because you can probably be happy for about US$20, rather than having to spend US$200 or more for a professional-grade video card with two independent video outputs. -- David Maze [EMAIL PROTECTED] http://people.debian.org/~dmaze/ "Theoretical politics is interesting.
