[Jukka Niiranen <jukka@xxxxxxxxxxx>]

Acer has confirmed me that they have hardware issues with Acer V3-371 's
touchpad mouse.

I contacted Acer's support here in Finland and immediately after
describing the problem on the phone I received a RMA number to send the
device for repairs. Acer repaired the device and returned it to me. The
repair note said that grounding of the touchpad mouse had been fixed.

Unfortunately the problem came back in about two weeks. Acer took the
laptop back for repairs again. This time they changed  entire touchpad
to another one from another device manufacturer. The device is now
working normally. Let's hope it keeps that way.

Best Regards, Jukka

Title:
  [Acer Aspire V3-371] Sometimes, cursor jumps around if touchpad is in
  use

Status in linux package in Ubuntu:
  Triaged

Bug description:
  If using the touchpad, the cursor jumps around on the screen. It seems
  to me that there are also some events (like clicks) that get fired.

  This issue can be worked around by disabling and enabling the touchpad
  (pressing Fn+F7 twice) but it will reappear after a certain amount of
  time.
