Hi, I'd like to profile a laptop display. As such it doesn't have all the controls typical of an external monitor, so I cannot control Brightness, Contrast, RGB values (gain and offset), and so on. Thus I cannot perform the calibration step as described in the documentation tutorial. I run GNU/Linux and an Eye-One Display 2. I tried to use the backlit illumination (even if the precision was low.. but better than anything) to control the brightness and to modify the RGB values by using xgamma after launching dispcal. However, it seems that xgamma is not effective at all while dispcal is running. How might I proceed to perform this step? Regards Marco
