nouveau - NVIDIA video driver
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.
driver supports PCI, PCI-Express and AGP video cards based on
the following NVIDIA chips:
- RIVA TNT
- RIVA TNT2
- GeForce 256, QUADRO
- GeForce2, QUADRO2
- NV11 & NV15
- GeForce3, QUADRO DCC
- 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
- G80, G84, G86, G92, G94, G96, G98, G200, GT215, GT216,
GT218, MCP77, MCP79, MCP89
- GeForce 4XX, 5XX
- GF100, GF104, GF106, GF108, GF110, GF114, GF116, GF117,
- GeForce 6XX, 7XX
- GK104, GK106, GK107, GK110, GK208
- GeForce GTX 750
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
- Option "HWCursor"
- Enable or disable the HW cursor. Default: on.
- Option "AccelMethod"
- Specify the acceleration method. One of "none",
or "exa". Default: exa.
- Option "NoAccel"
- Disable or enable acceleration. Default: acceleration is
- Option "ShadowFB"
- Enable or disable use of the shadow framebuffer layer.
- Option "WrappedFB"
- Enable or disable wfb, only affects nv50+. Useful for some
legacy configurations where high rendering latency is perceived. Default:
wfb is disabled.
- Option "GLXVBlank"
- 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"
- 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
- Option "PageFlip"
- Enable DRI2 page flipping. Default: on.
- Option "SwapLimit"
- 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
- Option "DRI"
- 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.
Under glamor acceleration DRI3 is always enabled if supported, as glamor
currently does not support DRI2. Default: 2 on exa, 3 on glamor.
