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", 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.
Default: 1.

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. Default: 2.
