Does it work after or while running a glx program? I had some problems with this on a laptop. VSync worked when an external monitor was connected or when running glxgears. To get around it I had to turn off or enable something in the driver source. I believe they turn off interrupts on vblank to save power. This should really become an option in the xorg file. Maybe it already is for the newest driver? Theo _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
