Hi,

Just switched to Ubuntu, and I'm trying to adjust the white point (monitor's color temperature) on my laptop but I have no idea how. I tried using LProf but Color Management won't load the profiles. I know you can change gamma by using xgamma, is there any way to change the white point manually as well?

Thanks

Not sure what is your purpose to change the color temperature, but maybe Redshift could be adapted to your needs if you know what is your target temperature. (Read the command line configuration options).

Thanks a lot, that really worked! My laptop monitor was too bright and i wasn't able to find a way to change it.

There is also a GUI for redshift , located here
