FOSS monitor calibrator?
windows has built it monitor calibration, anything like it for Linux? basically to adjust gamma and rgb balabce
Gamma can be adjusted with xrandr.
If you want to do a proper color calibration, lookup "color management" for your distro or desktop environment. You can load an ICC color profile, but you will need a colorimeter or spectrometer to create one.
see idc about it being color accurate, just looking a big better. gamma is the main issue tho, so thanks
