Default Re: Ubuntu, VLC, VSync and video tearing...

I can confirm similar issue: I have dualhead TwinView setup and VSync is working only on default notebook display. Probably problem is with different refresh rates (DFP0: 59,94Hz; DFP1: 59,88Hz).

I found this code for change VSYNC output (VDPAU/OpenGL):
Code:
export VDPAU_NVIDIA_SYNC_DISPLAY_DEVICE="DFP-1"
export __VDPAU_NVIDIA_SYNC_DISPLAY_DEVICE="DFP-1"
export GL_SYNC_TO_VBLANK=1
export __GL_SYNC_TO_VBLANK=1
export GL_SYNC_DISPLAY_DEVICE="DFP-1"
export __GL_SYNC_DISPLAY_DEVICE="DFP-1"
It's working perfectly, although the best solution is to have all monitors without tearing but for me this is sufficient.
