Use the four sliders to define the gamma correction either as a single value, or separately for the red, green and blue components. The X-Server default setting for gamma is 1.00 (Mac 1.80, WinXX 2.20). The test images help you to find proper settings.
To store the gamma settings system wide, enable the option 'Store settings to XF86Config'. The system settings will be restored at next X-Server startup. You need root access to use this option. Use this if you want to correct the gamma settings for all users and graphical environments on this machine.
To store the gamma settings to your personal TDE configuration, do not enable that option. The user settings will be restored at next TDE startup and replace temporary the system gamma settings. The system settings are not removed by that and will be restored at next X-Server startup.
On multi head systems, select the screen you want to alter with the combo box. This will also work with xinerama enabled. If you want to set all screens to the same gamma values, enable the 'Sync screens' option. On systems with only one screen this option will take no effect.
