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 moni-
	      tor 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 framer-
	      ate, 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	specifica-
	      tion.
	      Default: 2 for XOrg 1.12+, 1 for older servers.
