fbdev - video driver for framebuffer device
fbdev 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
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
Please refer to xorg.conf(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 " -scanpci" to
figure out the correct values.
