Hi list,
is it possible to synchronise the drawing process to the vsync cycle of the
graphics
card from user level?

Or should I try to modify driver/linux/ogp_skel.c to my needs?


I want to have a program that consecutive draws numbers on the framebuffer,
so that
every frame displays the following integer. Then I want to use a camera to
capture these
images.

I had a really hard time when I tried to do this with Nvidia or ATI cards
and I think I still haven't solved it.

Regards, Martin
