You must have compiz disabled though, xvideo sync NEVER works with compiz enabled even with only one monitor (I seriously hope this is something the nvidia devs are planning to fix very soon).
Opengl sync only ever works on one of the monitors if both are enabled. If only one is enabled, it works on that one. It would be nice to have an opengl monitor sync option like the xvideo sync option which decides which monitor to sync to.
Actually, I'm wrong. Opengl sync worked a while ago, maybe with the 180.27 driver or something like that, but with the 185.13 it seems to be broken again on dual monitors. Xv sync works fine though still, unless an opengl application is running at the same time on the other monitor, but this breaks vsync even in windows.
