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.
The fbdev driver supports all hardware where
a framebuffer driver is available. fbdev uses the os-specific submodule fbdevhw(4)
to talk to the kernel device driver. Currently a fbdevhw module is available
for linux.
Please refer to XF86Config(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 section of the config file. The 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.
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.
The following driver Options
are supported:
- Option "fbdev" "string"
- The framebuffer device to use. Default:
/dev/fb0.
- Option "ShadowFB" "boolean"
- Enable or disable use of the shadow
framebuffer layer. See shadowfb(4)
for further information. Default: on.
