XFBS(1)                              BSD                               XFBS(1)



NAME
     xfbs - select which window is allowed to fast buffer swap

SYNOPSIS
     xfbs [-help] [-toggle] [-on] [-off]

DESCRIPTION
     The xfbs program lets you control which windows have fast buffer swap
     enabled.  On some graphic devices, fast double buffer swapping is
     supported on only a limited number of windows.  When more than one
     application attempts to use GPR's double buffering feature, the
     applications will collide, resulting in an incorrect buffer display for
     both applications.  For those devices, this command allows the user to
     select which client uses the fast buffer mechanism.

     The user selects the target window with the mouse by moving the cursor to
     the desired window and clicking any mouse button.

     The Display Manager accepts a similar command: "fbs".

     If no options are specified, the default is to enable fast buffer
     swapping. Initially, applications have fast buffer swap enabled.

OPTIONS
     The various options are as follows:

     -help
          Print a usage message and exit.

     -on  Enable fast buffer swap for the indicated window.

     -off Disable fast buffer swap for the indicated window.

     -toggle
          Toggle the current state of fast buffer swap for the indicated
          window.
