24. All visual types are supported for depth 8, and TrueColor visual
is supported for the other depths. RandR 1.2 is supported.

available. modesetting uses the Linux DRM KMS ioctls and dumb object
create/map.
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 sec‐
tion of the config file. The modesetting driver can pick up the cur‐
rently 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 sec‐
tion. 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 "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 par‐
ticular 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.
