|MODESETTING(4)||Device Drivers Manual||MODESETTING(4)|
Section "Device" Identifier "devname" Driver "modesetting" BusID "pci:bus:dev:func" ... EndSection
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 "SWcursor" "boolean"
- Selects software cursor. The default is off.
- 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.
- Option "DoubleShadow" "boolean"
- Double-buffer shadow updates. When enabled, the driver will keep two copies of the shadow framebuffer. When the shadow framebuffer is flushed, the old and new versions of the shadow are compared, and only tiles that have actually changed are uploaded to the device. This is an optimization for server-class GPUs with a remote display function (typically VNC), where remote updates are triggered by any framebuffer write, so minimizing the amount of data uploaded is crucial. This defaults to enabled for ASPEED and Matrox G200 devices, and disabled otherwise.
- Option "AccelMethod" "string"
- One of "glamor" or "none". Default: glamor.
- Option "PageFlip" "boolean"
- Enable DRI3 page flipping. The default is 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 must 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.
