I can't change the brightness is CS:S too. I'm using xgamma -gamma for the screen to become brighter. I have only that issue in the whole game. And the one with the messy fonts too (probably everyone has that one).
And I'm using bumblebee as well (latest versions on Arch)
I'm using primus as bridge by the way (because it's a lot faster)
Hello guys!
After updating the Mesa lib from 8 to 9, libc 2.13 to 2.17 and Intel drivers ALL THE GLITCHES ARE GONE! Running Steam stock (no fancy startup scripts), overlay working and running ALL the games with primus (Optimus)!
(I think my system was a little outdated lol)
Greetings!

Hello guys!
First of all, the steam linux client in each release becomes better and better! In last release (2013-03-22) the steam overlay started working "magically" in my optimus system when I launch the games through Steam! This is great! The steam client is smart enough to be able to start the games and the overlay using primusrun, i.e., being running and processed in the Nvidia gpu.
But with that, the images in all the source engine based games (only TF2, CSS, HL2DM currently available in linux) are extremely dark. It seems to be or a gamma issue or some rendering problem. Changing the gamma on the in-game video properties does not work at all. Serious Sam 3 BFE has glitches too: lost of detail in illumination and textures. Below some images to illustrate what I'm saying:

What it could be?
Thank you for your support, guys!

The script I'm using to launch the source engine based games without overlay is this (with changes to load game from game like TF2, CSS, etc):
