[vox-tech] Synaptics driver problem on Lenovo Thinkpad e455

[Bill Kendrick]

I dont have the laptop in front of me, but over on:

  https://wiki.archlinux.org/index.php/Lenovo_Thinkpad_Edge_E455

I see:

  ClickPad
  The clickpad that is used is from Alps. Specifically, it uses Alps
  protocol 8 which has initial support in kernel 4.1. While basic
  functionality works with kernels less than 4.1, there may be issues
  that occur with use in kernel less than 4.1.

  For more advance features such as Vertical Edge Scrolling, see
  Touchpad Synaptics. An interesting quirk that occurs is that in order
  to be able to use Vertical, or Horizontal, Edge Scrolling you have to
  enable Two Finger Scrolling. Setting only the Edge Scrolling option in
  xorg doesn't enable it.


And:

lists:

  Unknown SynPS/2 Synaptics TouchPad


Trying to remember 2 months ago, I recall being able to either
disable the whole PS/2 mouse system (which disabled the TrackPoint, too),
or enable everything.  No way of using _just_ the TrackPoint.

I'll dig around more, hopefully soon, and post what I find.
Thanks!
