NAME

xvidtune - video mode tuner for XFree86

SYNOPSIS

xvidtune [ -prev | -next | -unlock | -query | -saver suspendtime [ offtime ] ] [ -toolkitoption ... ]

DESCRIPTION

Xvidtune is a client interface to the XFree86 X server video mode extension (XFree86-VidModeExtension).

When given one of the non-toolkit options, xvidtune provides a command line interface to either switch the video mode or get/set monitor power saver timeouts.

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 XF86Config file.

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
Adjust the video mode so that the display will be moved in the appropriate direction.

Wider
Narrower
Shorter
Taller
Adjust the video mode so that the display size is altered appropriately.

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 immediately. 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.

Show
Print the currently selected settings to stdout in XF86Config "Modeline" format. The primary selection is similarly set.

Next
Switch the Xserver to the next video mode.

Prev
Switch the Xserver to the previous video mode.

For some S3-based cards (964 and 968) the following are also available:

InvertVCLK
Change the VCLK invert/non-invert state.

EarlySC Change the Early SC state. This affects screen wrapping.

BlankDelay1
BlankDelay2
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 XF86Config, e.g. using blank_delay "*" 0

OPTIONS

xvidtune accepts the standard X Toolkit command line options as well as the following:

-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.

-saver suspendtime [offtime]
Set the ``suspend'' and ``off'' screensaver inactivity timeouts. The values are in seconds.

-query
Display the monitor parameters and extended screensaver timeouts.
