NAME

       xvidtune - video mode tuner for XFree86


SYNOPSIS

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

       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 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 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  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.

       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:

       -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.

BUGS

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