[Linux] Can't adjust Gamma/Brightness

[EnforcerZhukov]

Hi dudes. I have Team Fortress running OK (with nouveau drivers, hu-ha!), but i've got a little and annoying problem: i can't increase the Gamma. Game looks too dark, VERY dark. I setted up gamma level to maximum and it doesn't change. Also i setted the gamma to the minimum level and doesn't change.

Any idea? Thanks!

Still not fixed!

I have never tried adjusting gamma in any game. Does your monitor itself have brightness and contrast settings. I use an HDTV as monitor and use DVE (Digital Video Essentials) DVD or BlueRay to initially adjust it in general.

Which Linux distribution are you running and what video card/chip? There may still be alternate nvidia 173 drivers available for older cards, but the 96 driver for really old cards might not be in current Linux versions.

I have been running Linux Steam in 64-bit Ubuntu 12.04 with GTX 550 Ti using various nvidia drivers @ 1080p since Jan 2013, but recently upgraded to 64-bit Ubuntu 14.04 with GTX 750 Ti using nvidia 346 drivers from ppa repo.

Nouveau or some older nvidia drivers may not support the new Maxwell chip in GTX 750 or 9xx series cards. I discovered that when installing 14.04 and the old 304 driver of nvidia-current package did not work.

I don't know, i changed a long time ago my GPU, now I use an AMD HD7870 but ironically, Steam doesn't start under Linux with the AMD drivers :V

Hey! I know this thread is old. So I recently found a solution to those facing the problem. So what you need to do is:

1. Install xrandr
2. go to your tf2 directory

 ~/.local/share/Steam/steamapps/common/Team Fortress 2/ 

and edit the file hl2.sh then add the line:

 xrandr --output output_name --gamma 1.6:1.6:1.6  

just above

STATUS = 42

3. and then add

 xrandr --output output_name --gamma 1:1:1 

above

 exit $STATUS 

------------------------------------------------------------------------------------------------------------------------------------------
You can find your output_name by running:

$ xrandr

# $PWD

GAMEROOT=$(cd "${0%/*}" && echo $PWD)

#determine platform
