Dear fellows,

can I synchronize buffer swapping with refresh rate/vsync on XFree86 4 in Linux? If so, how do I do?

Specific HW/SW, RedHat 6.2, XFree86 4.0.0, nVidia OpenGL driver 0.9-3, Absolute Multimedia GeForce 2 (32 MB).

Short answer: I don't know.

Long answer: I believe swap control under Windows is done w/ a wgl extension, so the place to look for such functionality under Linux would be in the GLX extensions.

I've got a very similar setup to you and just tried to query the GLX extension string - it returned NULL. So either I did it wrong, or no extensions are exported yet by the NVIDIA driver. I was planning on playing around with the latest G400 and V3 DRI drivers this weekend, so maybe that will shed some light on things.

Cheers,
Mark
