Not sure I agree with this statement, given DPMS stands for *Display* Power Management Signaling, but whatever. > but before I try to hack up the fix, I would like to hear some > suggestions on what the "right" thing to do would be. How about something like this: If the swap can't be scheduled using a vertical blank event, because the relevant CRTC isn't running, check if the window's swap interval has elapsed since the last swap (using the refresh rate of the relevant CRTC's current / last set mode). If it hasn't, suspend the client until it has before doing the swap with a blit. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Debian, X and DRI developer _______________________________________________ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org http://lists.x.org/mailman/listinfo/xorg-driver-ati
