nouveau — NVIDIA video driver
Section "Device" Identifier "devname" Driver "nouveau" ... EndSection
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.
The nouveau 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
- 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, GF119
- 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 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". Default: exa.
- 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.
- 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 supported. Under glamor acceleration DRI3 is always enabled if supported, as glamor currently does not support DRI2. Default: 2 on exa, 3 on glamor.
