     xvidtune - video mode tuner for XFree86


     xvidtune [ -show | -prev | -next | -unlock ] [ -toolkitop-
     tion ... ]


     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.

     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 inclu-
     sion in an XF86Config file.

     Normally the XFree86 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 press-
     ing 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 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 selec-
               tion 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

               Change the VCLK invert/non-invert state.

     EarlySC   Change the Early SC state.  This affects screen

               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


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

     -show     Print the current settings to stdout in XF86Config
               "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 xvid-
     tune clients to write new modes, could be better.
