Date: Wed, 9 Apr 2003 18:21:33 -0230 From: Stephen Anthony <stephena@roadrunner.nf.net> Subject: [SDL] First patch concerning 4.3 and refresh rates OK, here's my first draft of the patch for the above subject. A short explanation: X 4.3 introduces many more modelines than older versions. This would be fine, except it introduces many modes with the *same* resolution but different refresh rates. And SDL won't necessarily pick the one with the highest refresh rate. So this patch restores SDL to X 4.2 functionality. That is, there is only ever one refresh rate *per* resolution, and it is the highest possible. This functionality can be totally disabled by using the environment variable 'SDL_VIDEO_X11_USE_ALL_MODES' set equal to 1.
