Reverted darwin/bundle/**/Credits.rtf to XFree86 versions to avoid
future conflicts on ASCII but not humal readable files. (There should
probably be separate CreditsXorg.rtf files) (Egbert Eich).

.SH DESCRIPTION
|
|
.B fbdev
|
|
is an XFree86 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 XF86Config(__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 "XFree86 -scanpci"
|
|
to figure out the correct values.
|
|
.PP
|
|

|
|
