I own a Razer Anansi keyboard and recently installed 13.04 after running 12.04 for over a year.

On 12.04 I used xmodmap to map the thumb and macro keys to do useful stuff for me. This solution is based on keycodes which are triggered when a key is recognized.

The problem is that on 13.04 this does not work for all keys anymore. The thumb keys T2, T3 and T4 (i.e. the middle 3 ones on the top of the 2 rows) in particular don't generate keycodes anymore while the rest still does.

Now this is not completely surprising: pressing the affected keys in Unity generates notifications for what looks like Unity touchpad notifications.

How can I shut that touchpad-subsystem up once and for all and give my keyboard keys back to my keyboard? Ideally I'd like to be able to use my .Xmodmap file again in 13.04 (and beyond) as that seems to me the most simple solution, but working alternatives are also welcome.
