Public bug reported:
The latest kernel update in 12.04 brought with it a backported driver
for Sentelic touchpads. However, this driver is causing extremely
erratic behaviour. Particularly, two-finger scrolling causes web
pages/etc to jump around eratically. Two-finger tap to right click is
also not working.
