Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.0 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 bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  Sometimes, cursor jumps around if touchpad is in use

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  If using the touchpad, the cursor jumps around on the screen. It seems
  to me that there are also some events (like clicks) that get fired.
  This issue can be worked around by disabling and enabling the touchpad
  (pressing Fn+F7 twice) but it will reappear after a certain amount of
  time.

  I have already tried to use some mainline kernels from
  http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D. I have tried
  v3.18-rc2-utopic, v3.18-rc1-utopic and v3.17.1-utopic. Either I could
  not boot into the specified kernel or the bug still existed.

  If there is any more information I could give or any debugging work
  that I could do, please let me know.
