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

       Option "AccelMethod" "string"
              Specify  the  acceleration method. One of "none", "exa", or "glamor". Default: exa,
              except for GMxxx which default to glamor.

       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: on.

       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: 1.
