<H2>DESCRIPTION</H2>
|
|
|
|
<B>fbdev</B>
|
|
|
|
is an Xorg driver for framebuffer devices. This is a non-accelerated
|
|
driver, the following framebuffer depths are supported: 8, 15, 16, 24.
|
|
All visual types are supported for depth 8, and TrueColor visual is
|
|
supported for the other depths. Multi-head configurations are supported.
|
|

|
|
<H2>SUPPORTED HARDWARE</H2>
|
|
|
|
The
|
|
<B>fbdev</B>
|
|
|
|
driver supports all hardware where a framebuffer driver is available.
|
|
fbdev uses the os-specific submodule <A HREF="/cgi-bin/man/man2html?4+fbdevhw">fbdevhw</A>(4) to talk
|
|
to the kernel
|
|
device driver. Currently a fbdevhw module is available for linux.

|
<H2>CONFIGURATION DETAILS</H2>
|
|
|
|
Please refer to <A HREF="/cgi-bin/man/man2html?5+xorg.conf">xorg.conf</A>(5) for general configuration
|
|
details. This section only covers configuration details specific to
|
|
this driver.
|
|
<P>
|
|
|
|
For this driver it is not required to specify modes in the screen
|
|
section of the config file. The
|
|
<B>fbdev</B>
|
|
|
|
driver can pick up the currently used video mode from the framebuffer
|
|
driver and will use it if there are no video modes configured.
|
|
<P>
|
|
|
|
For PCI boards you might have to add a BusID line to the Device
|
|
section. See above for a sample line.
|
|
<P>
|
|
|
|
The following driver
|
|
<B>Options</B>
|
