Updated: xvidtune 1.0.3
Xvidtune is a client interface to the X server video mode extension (XFree86-VidModeExtension).
When given one of the non-toolkit options, xvidtune provides a command line interface to either print or switch the video mode.
Without any options (or with only toolkit options) it presents the user with various buttons and sliders that can be used to interactively adjust existing video modes. It will also print the settings in a format suitable for inclusion in an xorg.conf file.
Normally the Xorg X servers only allow changes to be made with the XFree86-VidModeExtension from clients connected via a local connection type.
Note: The original mode settings can be restored by pressing the `R' key, and this can be used to restore a stable screen in situations where the screen becomes unreadable.
The available buttons are:
Left Right Up Down

For S3-864/868 based cards InvertVCLK and BlankDelay1 may be useful. For S3 Trio32/Trio64 cards only InvertVCLK is available. At the moment there are no default settings available for these chips in the video mode extension and thus this feature is disabled in xvidtune. It can be enabled by setting any of the optional S3 commands in the screen section of xorg.conf, e.g. using
xvidtune accepts the standard X Toolkit command line options as well as the following:

X Error handling, i.e. when the server does not allow xvidtune clients to write new modes, could be better.
