Title: Brightness problems
Post by: tskuzzy on February 16, 2010, 10:41:23 pm

Ok, so I just recently switched over to the open-source radeon driver from the fglrx driver for my graphics card. After a day of debugging, I finally managed to get 3D acceleration up and running with the radeon driver.

However I noticed a significant brightness decrease in Tremulous. Adjusting r_gamma changes absolutely nothing. Even lightmap displays everything rather darker than before. Any way I can fix this?

Yup! If I set it to 2 (my r_gamma setting), everything in trem is back to normal. However, as expected, everything else is also brightened on my screen XD

So I guess for some reason the Tremulous gamma correction isn't working for me. :S

yeah this has been reported before, but it's most likely a bug in xorg (or possibly sdl).

Hm that might be it. I upgraded to xorg 1.7 along with that driver change.
