<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.
<A NAME="lbAE">&nbsp;</A>
<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.
<A NAME="lbAF">&nbsp;</A>
<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
