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:

       RIVA TNT              NV4

       RIVA TNT2             NV5

       GeForce 256, QUADRO   NV10

       GeForce2, QUADRO2     NV11 & NV15

       GeForce3, QUADRO DCC  NV20

       nForce, nForce2       NV1A, NV1F

       GeForce4, QUADRO4     NV17, NV18, NV25, NV28

       GeForce FX, QUADRO FX NV30, NV31, NV34, NV35, NV36, NV37, NV38

       GeForce 6XXX          NV40, NV41, NV43, NV44, NV45, C51

       GeForce 7XXX          G70, G71, G72, G73

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 "HWCursor" "boolean"
              Enable or disable the HW cursor.  Default: on.

       Option "NoAccel" "boolean"
              Disable or enable acceleration.  Default: acceleration is enabled.

       Option "ShadowFB" "boolean"
              Enable or disable use of the shadow framebuffer layer.  Default: off.

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

       Option "GLXVBlank" "boolean"
              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: off.

       Option "ZaphodHeads" "string"
              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 "ZaphodHeads" "LVDS,VGA-0" will assign xrandr outputs LVDS and VGA-0 to this
              instance of the driver.

       Option "PageFlip" "boolean"
              Enable DRI2 page flipping. Default: on.

       Option "SwapLimit" "integer"
              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  currently 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: 2 for XOrg 1.12+, 1 for older servers.
