Sorry previous comment should read:-
Also I rolled back the kernel through -73, -72, -71 and -70 and tested
each to see if they still worked like they used to but they all now fail
to recognise the SynPS/2 Synaptics Touchpad driver.

Hi All,
I do not want to suggest that more competent people than myself could be wrong
but...
This bug (Synaptics touchpad not recognised) originally appeared when I
upgraded from 3.13.0-74.118 to -76.120 however my recent comment about
-74.118 suddenly suffering from the same problem (following

After a normal apt-get update today the touchpad in kernel 3.13.0-74,
-73, -72 ,-71 and -70 are broken as well, so this bug appears not to be
in the kernel but elsewhere.
Just to recap. After an update today (15/2/2016) under kernel 3.13.0-74
(which was working) the synaptics touchpad is not
John Leake, could you please advise to where precisely you are stuck? As
the article is written for people who have no computer knowledge
whatsoever, the disconnect is not understood.

Further context and not to be interpreted as a rant: It has taken me
years to get away from M$ and find an alternative that I can live with
(unity excluded). I filed the report not as a criticism of its quality
but to help/assist in the progress towards a better experience for all
users. I can
Perhaps it has something to do with the fact that I am 61 years old and
not as sharp as I used to be. By the time I had waded through all the
content and followed each link for further information I found myself
lost at sea (ie I had completely lost my bearings) and had to start all
over again
Hi Chris (or any one else),
I have a question about the Ubuntu bug fixing process.
Since what is being asked of me is beyond my capabilities, then I am
unable to mark the bug an New. Does this mean that the status will just
stay as Incomplete until it expires like lots of similar confirmed bugs
Glad to assist but this is on the edge of my experience. I had the same
problems with the header dependencies when installing, however 4.5-rc1
booted and the touchpad is still not recognised. I noticed that there
was a TPM (6) error on boot. Sorry I do not know how to provide you
with any more

OK so I managed to update the bios.

Still fails on 76, 4.4 and 4.5
The 76 boot is worse (no wifi and screen resolution screwed up).
The boot error TPM(6) occurs when attempting to read pcr value.

The boot error TPM(6) that occurs when attempting to read pcr value is
not encountered if the security chip is disabled in the bios settings.
This showed up in 4.4 and 4.5

John Leake, the next step is to fully commit bisect from kernel
3.13.0-74 to 3.13.0-76 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
Correction, the 76 boot was not worse, I forgot to install linux extra.
The touchpad bug still exists in 76 however.

Hi Chris, I have read the bisect info link and I am sorry to say it is
well beyond my capability. For a start I have never built a kernel
before and have only ever used git clone in order to download and browse
through small source projects off-line.
Having said that it cannot be very time

Thank you for the response. As I stated earlier I am on the edge of my
experience and well out of my comfort zone. It took me two whole days to
find and isolate the problem to the -76 release.
I looked at the first link and cannot find a bios update for linux or
any help on how to do this. Your
I failed to overcome linux-header dependencies despite uninstalling
virtualbox however v4.4 did boot but the mousepad was not recognised.
Hope this is of some use.

Bugs,
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.4 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix
This also breaks all Virtualbox clients.
