Configuration Details

Please refer to xorg.conf(5) for general configuration details. This section only covers configuration details specific to this driver.

For this driver it is not required to specify modes in the screen section of the config file. The modesetting driver can pick up the currently used video mode from the kernel driver and will use it if there are no video modes configured.

For PCI boards you might have to add a BusID line to the Device section. See above for a sample line.

The following driver Options are supported:

Option kmsdev string
The framebuffer device to use. Default: /dev/dri/card0.
Option ShadowFB boolean
Enable or disable use of the shadow framebuffer layer. Default: on.
