     DESCRIPTION
          nouveau is an Xorg driver for NVIDIA video cards.  The
          driver supports 2D acceleration and provides support for the
          following framebuffer depths: (15,) 16  and 24.  TrueColor
          visuals are supported for these depths.

     SUPPORTED HARDWARE
          The nouveau driver supports PCI, PCI-Express and AGP video
          cards based on the following NVIDIA chips:

     CONFIGURATION DETAILS
          Please refer to xorg.conf(5) for general configuration
          details.  This section only covers configuration details
          specific to this driver.

          The driver auto-detects the chipset type and the amount of
          video memory present for all chips.

          The following driver Options are supported:

          Option 34HWCursor34 34boolean34
               Enable or disable the HW cursor.  Default: on.

          Option 34AccelMethod34 34string34
               Specify the acceleration method. One of 34none34, or
               34exa34. Default: exa.

          Option 34NoAccel34 34boolean34
               Disable or enable acceleration.  Default: acceleration
               is enabled.

          Option 34ShadowFB34 34boolean34
               Enable or disable use of the shadow framebuffer layer.
               Default: off.

          Option 34WrappedFB34 34boolean34
               Enable or disable wfb, only affects nv50+. Useful for
               some legacy configurations where high rendering latency
               is perceived.  Default: wfb is disabled.

          Option 34GLXVBlank34 34boolean34
               Synchronize GLX clients to VBlank. Useful where tearing
               is a problem, harmful if the GPU isn't fast enough to
               keep up with the monitor refresh rate. Default: on.

          Option 34ZaphodHeads34 34string34
               Specify the randr output(s) to use with zaphod mode for
               a particular driver instance.  If you use this option
               you most use this option for all instances of the
               driver.
               For example: Option 34ZaphodHeads34 34LVDS,VGA-034 will

     NOUVEAU(4)         (xf86-video-nouveau 1.0.17)         NOUVEAU(4)

               assign xrandr outputs LVDS and VGA-0 to this instance
               of the driver.

          Option 34PageFlip34 34boolean34
               Enable DRI2 page flipping. Default: on.

          Option 34SwapLimit34 34integer34
               Set maximum allowed number of pending OpenGL double-
               buffer swaps for a drawable before a client is blocked.
               A value of 1 corresponds to double-buffering. A value
               of 2 corresponds to triple-buffering. Higher values may
               allow higher framerate, but also increase lag for
               interactive applications, e.g., games. Nouveau cur-
               rently reliably supports a maximum value of 2 on XOrg
               1.12+. A maximum setting of 2 on older x-servers is
               allowed, but it will break conformance with the OpenML
               OML_sync_control specification and will cause failure
               of software that relies on correct presentation timing
               behaviour as defined in that specification.
               Default: 1.

          Option 34DRI34 34integer34
               Define the maximum level of DRI to enable. Valid values
               are 2 or 3.  exa acceleration will honor the maximum
               level if it is supported.  Default: 2.
