xvidtune [ -show | -prev | -next | -unlock ] [ -toolkitoption ... ]
Xvidtune is a client interface to the X server video mode extension
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 for-
mat 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
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:
Adjust the video mode so that the display will be moved in
the appropriate direction.
Adjust the video mode so that the display size is altered
Quit Exit the program.
Apply Adjust the current video mode to match the selected settings.
Auto Cause the Up/Down/Right/Left, Wider/Narrower/Shorter/Taller,
Restore, and the special S3 buttons to be applied immedi-
ately. This button can be toggled.
Test Temporarily switch to the selected settings.
Restore Return the settings to their original values.
Fetch Query the server for its current settings.
EarlySC Change the Early SC state. This affects screen wrapping.
Set the blank delay values. This affects screen wrapping.
Acceptable values are in the range 0-7. The values may be
incremented or decremented with the `+' and `-' buttons, or
by pressing the `+' or `-' keys in the text field.
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
blank_delay "*" 0
xvidtune accepts the standard X Toolkit command line options as well as
-show Print the current settings to stdout in xorg.conf "Modeline"
format and exit.
-prev Switch the Xserver to the previous video mode.
-next Switch the Xserver to the next video mode.
-unlock Normally, xvidtune will disable the switching of video modes
via hot-keys while it is running. If for some reason the
program did not exit cleanly and they are still disabled, the
program can be re-run with this option to re-enable the mode
switching key combinations.

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