.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.
