["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

D Fine, at your earliest convenience, could you please test the latest
upstream kernel available from the very top line at the top of the page
from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release
names are irrelevant for testing, and please do not test the daily
folder)? Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow
additional upstream developers to examine the issue.

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Title:
  Touchpad intermittently stops working

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Touchpad intermittently stops working on lenovo carbon x1 (gen1)

  If I close the lid, or sometimes disable and then re-enable touchpad
  in BIOS, it may sometimes come back.  Sometimes running the software
  updater seems to fix or break it, but this may be incidental

  also perhaps incidental, im using virtualbox alot, and thats really
  the only thing new in my workflow.

  when it doesn't work, xinput list sometimes does not show the device.
  Once it shows, i can see properties in system settings -> mouse and
  touchpad', but that doesn't necessarily mean the touchpad is going to
  come alive.

  If it does start to work, it often works across several reboots.

  i've attached some additional files in a tarball:
      -- beforeaAndAfterLidClose -- this was a run of cat /proc/bus/input/devices before and after closing lid ... note that after closing and reopening, the TouchPad shows up.
      -- dmesg
      -- devices: a full '/cat/proc/bus/devices', obtained after the touchpad reappeared, which will show the vendor information
      -- Xorg.0.log
