Calix
About Calix
This is a program I made for myself. I worked for several years in graphic design and I was disappointed in the quality of desktop publishing software for Linux. I wanted an easy way to at least set the gamma curve so that it was at least halfway calibrated. I found the xgamma command-line tool and decided to write a front-end to it. It's written in Python and uses GTK for the widgets. It works out of the box on Ubuntu and should be easy to get the requirements for other distros.
