[Bug 747123] Re: [Natty] [Kubuntu] Alps touchpad scrolling does not work

[Scott Testerman]

Possibly related, the pressure required to register a mouse click when
tapping the pad varies wildly, for no apparent reason.  Sometimes the
tap requires only light pressure, as expected, while other times the tap
must be quite firm to register.  This is distinct from the behavior in
the preinstalled Windows 7.

I have had two different revisions of this same notebook, an Acer
7552G-6436, and unfortunately had to return the first due to a faulty
hard drive. The first version had a Synaptics touchpad which worked well
with the Natty Alpha series.  Both machines have identical
specifications for the touchpad in regards to features like gestures,
scrolling, etc.  As another interesting aside, the first revision used
an Atheros wifi chipset while this version uses Broadcom.

** Description changed:

  On a fresh install of Kubuntu Natty Beta 1, the touchpad on an Acer
  7552G-6436 is correctly detected as Alps. In Kubuntu 10.10 the Alps
  touchpad is only detected as a generic PS/2 mouse.
  
  Unfortunately, in System Settings > Input Devices > Touchpad, although
  "Vertical scrolling at right edge" is checked, scrolling still does not
- work.
