nouveau - NVIDIA video driver
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
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, MCP61
GeForce 7XXX G70, G71, G72, G73, MCP67, MCP68, MCP73
GeForce 8XXX, 9XXX, 2XX, 3XX

GeForce GTX 10XX GP102, GP104, GP106, GP107, GP108
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", or "exa".
Option "NoAccel" "boolean"
Disable or enable acceleration. Default: acceleration is
Option "ShadowFB" "boolean"
Enable or disable use of the shadow framebuffer layer. Default:
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 par-
ticular 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 cor-
responds 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 soft-
ware that relies on correct presentation timing behaviour as
defined in that specification.
Option "DRI" "integer"
Define the maximum level of DRI to enable. Valid values are 2 or
3. exa acceleration will honor the maximum level if it is sup-
ported. Default: 2.
