Hello,
Sure. Make sure that whatever kernel you're using has support built for it, load the module, and start up X. Make sure you're loading the dri module.
Strange - as I've got 2 graphics cards and 3 monitors, an el cheapo TNT2 and the G550. The desktop "on" the TNT2 shows OpenGL applications just fine, but the desktops "on" the G550 won't show OpenGL applications, also that Quake 3 just crashes on the G550, but runs fine on the TNT2.
Thanks very much for your help again Cheers - Piers
