    Question Cannot change gamma in games (HD 4870)

    Hi

    I'm using xcalib to calibrate my screen at boot time. System is 64-bit ubuntu 10.04. My screencard is ATI HD 4870. Now the problem is that when I want to run a game form f.ex Frictional Games (Penumbra or Amnesia), I cannot seem to be able to change the gamma level. The games are OpenGl games. Is this because I use the xcalib or do I need to upgrade my fglrx driver? I'm using the one packaged for ubuntu 10.04.

    I'm currently without internet due to some digging work by the neighbour ("&/%#"), so if it can be solved without upgrading the driver it would be nice.

    Try calibrating your gamma from the catalyst control center.
