Hi,
I am considering moving to Linux from Windows. However, one of the issues I have to solve is that of color correction. On windows, I achieve that with Intel graphics media accelerator, which allows me to adjust red, blue, and green colors through gamma, brightness, and contrast settings:

Are there similar color adjustment options available on Linux?

Thanks!

You can adjust that with xrandr and also with libxca. Although command line driven. The values are floating point where 1 is the default value, numbers > 1 is more, and < 1 is less.

For example for me to watch hulu and not have every thing in a shadow be solid black...

$ xrandr --output HDMI1 --brightness 0.95 --gamma 1.15:1.15:1.15

Where the #:#:# is RED:GREEN:BLUE values for gamma. AMD GPUs have the amdcccle tool, not sure what the newer version of that changed to. Nvidia GPUs have nvidia-config or nvidia-xconfig, not sure as I've never used one to any extent. Most of my current laptops are intel GPUs and I'm not sure if they have a gui tool or what it's called.

Great, that looks promising. Thanks a lot!
