  • fglrx 8.42.3: brightness problems in OpenGL game

    Since the upgrade to 8.42.3 no opengl game will accept any ingame brightness changes. I can change the gamma/brightness all I want, it doesnt change. Downgrading the driver is not that easy because of some conflicts with newer xorg. It's definitely the drivers fault, gamma change works with the open radeon driver. Has this been reported and is there a fix/workaround for this to come?

    Someone on the #ati channel on freenode told me this bug is know. Is it going to be fixed? Cause that's pretty heavy, virtually making it impossible to enjoy the game.

      it still exist in 7.11
      you can not change gamma in games

          right... if you didnt installed it

          here is my to work around this problem
          fglrx_xgamma -c 0 -gamma 1.8
          fglrx_xgamma -c 0 -gamma 1


          so it sets gamma to 1.8, runs tremulous.x86, when you quit it goes back to gamma 1.0
