GAMMApage is a program to adjust a monitor's gamma
setting, either fully or by color. It is capable
of setting gamma for most Linux distributions upon
login, including those using ATI fglrx_xgamma. It
works both for graphical logins or console logins.
It only requires write access to the user's home
directory, not to any system directories. It
includes "preparation" tips with white and black
point targets to make gamma corrections effective.
This is the pumped-up, Python/GTK version of
Monica.
