The subject pretty much sums up what I want to know.
As far as I know right now there's no support for 2d vsync and as
result I always get an annoying amount of tearing when using my
desktop, e.g. moving windows around. I know most people don't
notice/care about this but I guess I ha
Hello,
I have compiz + kde4 on Gentoo with nvidia drivers. My xorg.conf is
configured for laptop monitor. Xorg server is 1.6.3.901-r2 stable. VSync
in videos works on laptop monitor. If I enable external monitor/disable
laptop monitor through nvidia-settings gui I start to have VSync
problems
my applicaton is not synchronized with my display.

it does a wait for the vertical synchronization.
Where I can configure my application for it uses the pipe B for the VSync ?
Is it in the xorg.conf or elsewhere?

the 3D drawing frame
rate,
reported by glxgears, is exactly the VSYNC rate. The CPU usage is well down and
is definitely using DRI. When using the stock xf86-intel-video driver that
