+.SH NAME
+fbdev \- video driver for framebuffer device
+.SH SYNOPSIS
+.nf
+.B "Section \*qDevice\*q"
+.BI "  Identifier \*q"  devname \*q
+.B  "  Driver \*qfbdev\*q"
+.BI "  BusID  \*qpci:" bus : dev : func \*q
+\ \ ...
+.B EndSection
+.fi
+.SH DESCRIPTION
+.B fbdev
+is an __xservername__ 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.
+.SH SUPPORTED HARDWARE
+The 
+.B fbdev
+driver supports all hardware where a framebuffer driver is available.
+fbdev uses the os-specific submodule fbdevhw(__drivermansuffix__) to talk
+to the kernel
+device driver.  Currently a fbdevhw module is available for linux.
+.SH CONFIGURATION DETAILS
+Please refer to __xconfigfile__(__filemansuffix__) for general configuration
+details.  This section only covers configuration details specific to
+this driver.
+.PP
+For this driver it is not required to specify modes in the screen 
+section of the config file.  The
+.B fbdev
+driver can pick up the currently used video mode from the framebuffer 
+driver and will use it if there are no video modes configured.
+.PP
+For PCI boards you might have to add a BusID line to the Device
+section.  See above for a sample line.  You can use \*q\__xservername__
+-scanpci\*q
+to figure out the correct values.
+.PP
+The following driver 
+.B Options
+are supported:
+.TP
+.BI "Option \*qfbdev\*q \*q" string \*q
+The framebuffer device to use. Default: /dev/fb0.
+.TP
+.BI "Option \*qShadowFB\*q \*q" boolean \*q
+Enable or disable use of the shadow framebuffer layer.  Default: on.
+.TP
+.BI "Option \*qRotate\*q \*q" string \*q
+Enable rotation of the display. The supported values are "CW" (clockwise,
+90 degrees), "UD" (upside down, 180 degrees) and "CCW" (counter clockwise,
+270 degrees). Implies use of the shadow framebuffer layer.   Default: off.
+.SH "SEE ALSO"
+__xservername__(__appmansuffix__), __xconfigfile__(__filemansuffix__), Xserver(__appmansuffix__),
+X(__miscmansuffix__), fbdevhw(__drivermansuffix__)
