Bug Description

On a system76 gazelle9, the track pad sometimes fires off a click even when it is not pressed. This can happen when typing on the keyboard (not touching the trackpad) or when actually using the mouse but not clicking. Such events make it somewhat unsafe and inconvenient to use GUI applications that do not have an "undo" function for each possible action. Nothing seems to make the false clicks more or less likely to happen.

Lars Noodén, could you please test the latest upstream kernel available from the very top line at the top of the page (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-3.16-rc1

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

This hardware was not available to me prior to Trusty.

There is also #1245159 but that is on different hardware.

Could these be something with LXDE?

Lars Noodén, in order to test out GUI or version issue, could you please test http://cdimage.ubuntu.com/daily-live/current/ (live environment would be fine) and advise to the results?
