Title:
  [Acer Aspire One 725] Touchpad not working

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Touchpad will not work out of the box on this netbook. This is a
  regression from Oneiric to Precise+.

  a)WORKAROUND: Pushing Fn+F7 before login
  or
  b)WORKAROUND: Pushing Alt+Fn+F7 or Ctr+Fn+F7 after login makes the touchpad working. After reboot, I have to repeat a) or b) to get touchpad working again.
