Brightness problem with ATI cards
Every time...and mark my words, I want to make this clear. EVERY TIME I run bzflagon a computer with an ATI video card, the screen is too dark. I always have to go into the display options and increase the brightness. Even if I exit the game and reload it, the screen is ALWAYS too dark.
I have tried multiple computers. I seems that only the ATI cards are affected by this brighness bug.
I have tried X300 onboard, X800XL AGP and Rage Pro. All these cards have the brighness problem.
I never have problems with nVidia cards i.e MX440, FX5200, or Intel onboard graphics.
What is being done about this bug?

sounds more like an issue with the ATI video drivers, then it does a bug with the bzflag code.
As you state cards that use other drivers work fine.
There is no ATI specific code in bzflag, we simply ask openGL to set the gamma.
I would check and make sure you have the current drivers from ATI, and if so, report the problem to them.

then it would be a bug in the core ATI code. The drivers do share code between OSs.
I would report this to ATI with as much info as you can, our game is free so they can download it to evaluate the problem.
I went over the gamma code last night and didn't see anything that isn't to the openGL spec.

Here is a link to a dead thread that may help solve your problem, even if I couldn't solve mine.
