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.

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.
