NAME
     xvidtune - video mode tuner for Xorg

SYNOPSIS
     /usr/bin/xvidtune [ -show | -prev |  -next  |  -unlock  ]  [
     -toolkitoption ... ]

DESCRIPTION
     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 inclu-
     sion 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  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:

     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
               xorg.conf  "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
     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 xorg.conf, 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  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.

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