Brendan D., given this report is scoped to different model using 16.04 (and
your issue is not reproducible in 16.10), it will help immensely if you use the
computer the problem is reproducible with, and provide necessary debugging logs
by filing a new report with Ubuntu via a terminal:

Same issue here, running Ubuntu 17.10 on a Lenovo Thinkpad T440.
Touchpad + trackpoint move between these three states:
1) everything works fine: touch to click, touch pad, two finger
scroll/right-click and trackpoint
2) everything except for two-finger actions work
3) nothing works: touchpad +
I have the same problem here.
Now on Ubuntu 16.04.
But up until yesterday had it on 16.10.

Despite this, it wouldn't hurt to periodically test the latest mainline
kernel (now 4.5-rc7) while bisecting so that if a fix is identified, the
focus may be pivoted to this.

Hi again,
Problem still in affect. Not sure if you get the updates properly? This time I

penalvch,
I have begun testing with kernels ranging from 4.2.0 to 4.4.0. After booting
4.2.0 kernel I was about to start bisecting - but while reading the wiki I
realized the touchpad two finger scrolling had stopped working again while on
kernel 4.2.0. Would it really be necessary to start bise
niclas.kroon, the next step is to fully commit bisect from kernel 4.2 to
4.4 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ub
penalvch,
I confirm this issue did not occur prior to 16.04 upgrade.

UPDATE:
On kernel 4.5.0-040500rc6-generic the fault remains - the two finger scrolling
feature is dead, this also introduced the fault that the touchpad sometimes
does not work at all directly after boot. Marking as 'confirmed' and tagged;

Hi again,
This is funny, the problems are back again. Thats really weird - entire ~two
days without any issues. Then suddenly out of the blue touchpad stops working
again. Back to square one.

Hi,
Thank you for your reply penalvch. So I did something drastic because I got
tired of the issue and it hindered me in my school work to much. I simply
reinstalled the 16.04 from scratch removing the previous version Ubuntu 15.10
which was upgraded to 16.04. Likely something during that upgrad
niclas.kroon, in order to allow additional upstream developers to examine the
issue, at your earliest convenience, could you please test the latest upstream
kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ?
Please keep in mind the following:

I take my previous post back a little - the touchpad has stopped working
entirely now while on the new BIOS - However it takes much longer time
in between the faults from occuring now on the new bios. Instead of 1
hour its like once every 3-4th hour.
What steps can I take to further dive into this
Hi again,
After some testing I've concluded that the BIOS update did have good effect -
the touchpad never stops working entirely now. Only the two way scrolling
feature stops which is still kind of annoying. It appears to happen after
suspend-mode being activated and resumed.

Hi,
Thank you for your thourough answer this is my first time reporting a bug (I
think). I have taken your suggestion and upgraded the BIOS to version

reproduce otherwise I will take suggested action and mark as inv
