Public bug reported:
This is an intermittent issue that I have been experiencing with Ubuntu
15.10 (Unity) and an HP Envy x360 hybrid notebook.
Touchpad inputs suddenly begin to cause erratic outcomes. Making any
input with the touchpad often causes the cursor to appear near the top
right of the screen or in another unpredictable location. There are
phantom left and right clicks recorded without the user inputting them.
While trying to move the cursor to any particular place or to make some
other action, the cursor "dances" around the area or appears at an
extreme of the screen.
Touchscreen inputs and external mouse inputs continue to function
normally. As long as the user is not interacting with the touchpad at
all, then everything appears normal.
Only a full reboot appears sufficient to correct the error. I have not
been able to test hibernate/resume as a workaround, as hibernate is not
currently working on this machine. Logout/login and suspend-resume to
not appear to correct the problem.
This bug does not appear reliably after any particular action or period
of time. I have occasionally noticed it after a resume from suspend, but
it has also been present on boot or just in the middle of normal
operation. The logs posted with this bug were collected after an
appearance in the middle of normal use.
