The XFree86-FBDev package contains an X server for the generic frame
buffer device. This X server is usually the only choice for SPARC
machines, but also has some special capabilities that make it useful
on Intel platforms, especially laptops.
First, this X server can be used as a generic driver for a chipset
that does not yet have an Open Source driver (note that it will be
un-accelerated). Secondly, this X server "speaks" VESA protocols, so
it will produce the exact timing needed by projection systems. This
feature is handy for using your laptop to display a presentation on a
projection system on the road. Your regular X server may or may not
be in sync with the projection system, but the FBDev X server will
always work. Thirdly, this X server can produce a larger display, at
a higher resolution, for consoles on laptops.
