NAME
       xvidtune - video mode tuner for Xorg

SYNOPSIS
       xvidtune [ -show | -prev | -next | -unlock | -timeout sec ] [ -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 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	 ap‐
		 plied 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 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 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.

       -timeout sec
		 Set testmode timeout in seconds.

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