DESCRIPTION

     The xvctl utility retrieves the Xvideo extension attributes and allows
     the user to set them.

     For instance, this can be used to change the contrast or brightness of an
     external video program.

     The options are as follows:

     -d display
          affect the display named display, instead of the default display.

     -s screen
          affect screen # screen. By default, the first screen with video
          adaptors will be chosen.

     -A adaptor
          affect adaptor # adaptor. By default, the first display adaptor will
          be chosen.

     -a   list all the currently available gettable attributes.

     -n   suppress printing of the field name, only output the field value.
          Useful for setting shell variables.

     -w   required to set a variable. The name should be followed by an equal
          sign and the new value.
