xf86cfg - Graphical configuration tool for XFree86 4.0


xf86cfg [-xf86config XF86Config] [-toolkitoption ...]


Xf86cfg is a tool to configure XFree86 4.0, and can be used to either write the initial configuration file or make customizations to the current configuration.

When the DISPLAY environment variable is not set, xf86cfg will run the command XFree86 -configure to allow the xserver detect the hardware in the computer, and write an initial XF86Config file in the user's home directory. Then, it will start XFree86 and allow customizations.
If the DISPLAY environment variable is set, xf86cfg will read the default XF86Config, that may not be the same being used by the current server, and allow customizations.

Unless there is an Apply button in the current xf86cfg dialog, the changes made will take place the next time XFree86 is started.

Xf86cfg allows addition and configuration of new devices, such as video cards, monitors, keyboards and mouses.

Screen layout configuration for xinerama or traditional multi-head is also available.

Modelines can be configured or optimized.

AccessX basic configurations can be made in the xf86cfg's accessx section.
