No change when trying to change gamma lavel - Oblidor - 09-13-2010 Hi I have tried to change the gamma level to make the grey box almost not visible. But when I change the gamma value I see no change whatsoever. This applies to Amnesia and all the Penumbria games. I'm using the fglrx driver for Ati HD 4870 in Xorg (Ubuntu 10.04 64-bit). I also run xcalib at boot to calibrate the screen and this works. Does the xcalib prevent the the gamma change in the game? Anybody experiencing the same problems? I don't know if it is driver problem, setup problem or the games have some problems. Any hints much appreciated. RE: No change when trying to change gamma lavel - Urkle - 09-13-2010 It seems as though the ATI drivers do not support gamma changes via the SDL_SetGamma call, which performs an XF86VidModeSetGamma in X11. I see the same issue on my ATI HD 3000 card as well, but not on my Nvidia 7300.

Yes, seems gamma changes are not possible in game. I solved the problem by a small script: ------ #!/bin/sh xgamma -gamma 0.7 ./Amnesia.bin64 xgamma -gamma 1.0 ---- (from memory) Running this starts amnesia with the gamma level that works best for me. This also solved the ugly shadow effects I got due to that the gamma was too high. |
