[Bug 1431338] Re: Touchpad is not detected. Lenovo E550.
By the way, it seems that there are other issues with the ALPS
trackpoint which is used with the E550. With the trackpad working ok,
the trackpoint "stick" is slow and the configuration options for speed
and acceleration seem to not be available.
See http://www.thinkwiki.org/wiki/UltraNav or
http://wiki.ubuntuusers.de/Trackpoint#ALPS for some more details.
