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.
Wacom ExpressKeys supports the fairly recent additions of ExpressKeys, Touch Strips, and a Scroll Wheel on certain Wacom tablets. Specifically the Cintiq 21UX Interactive Pen Display, the Intuos3, and the Graphire4 tablets are supported through the XInput and XTest extensions in X. Using "xsetwacom", it can also provide an automatic change of stylus pressure sensitivity (a.k.a. PressCurve) when going from one program window to the next. This feature is independent of the connected tablet model. A graphical configuration tool named "wacom-config" is under development.
