It is fairly straightforward to get Linux distributions to boot and run on the XO, since it is a "just" an X86 computer. The XO has several unique features that require additional steps to enable.

This work is present in the Fedora adaptation that is the normal operating system for OLPC OS images. This page documents the changes that other Linux distributions require.

Input controls

Controlling the backlight

When the backliht is off the video becomes effectively high-res monochrome (?).

See http://dev.laptop.org/~pgf/brightness.sh.txt

Gamepad keys

You could run a very simple daemon that eavesdrops on an /dev/input/eventNN node in order to support XO's multi-media keyboard keys. if there's not already a packaged way of doing it.

The slider function keys

Stylus pad

The extended stylus pad either side of the track pad. Note this feature may be removed from future hardware.

Lid sensors

These need to trigger screen off or enter e-book mode.

EC interface

The embedded controller can provide battery info and charge status. This may show up under the power interfaces, may not have stable API.

Backlight controls (see http://dev.laptop.org/~pgf/brightness.sh.txt ).

Mesh mode

XO uses special firmware to implement a early draft of 802.11s mesh networking (??)

Hardware encryption engine

Camera details

Mic input

kmix sees the sound device, including DC input mode, which I didn't expect, but I haven't sucessfully recorded anything yet)
