Comment 25 for bug 1394869

I am having the exact same issue with my HP Stream 11's clickpad in Lubuntu 14.10. Cursor movement acts fine until I attempt or accidentally click the clickpad at which point no mouse clicks from any source will work properly (it triggers a click but only from the point where the last click was made and cannot be further adjusted).

Disabling the clickpad with the command:
xinput set-prop 11 "Device Enabled" 0
fixes the issue, but of course makes the clickpad nonfunctional.

I have never filed a bug report before so I do not know if I am helping or not. If I can be of more help, please let me know what I can do.
