Assuming 'Xorg 7.5' means xserver 1.6.x, I think this should be fixed in the current xserver 1.7.x releases. For SDL, the best solution would be to set the gamma ramp via the RandR extension when possible. Otherwise IIRC it needs to watch for a VidMode extension gamma ramp size of 0 and use XF86VidModeSetGamma() in that case. -- Earthling Michel Dänzer | http://www.vmware.com Libre software enthusiast | Debian, X and DRI developer _______________________________________________ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg
