Today, suddenly my Ubuntu 14.04 running on my HP Pavillion DV6 had the touchapd not working properly, at all.

I plugged an external mouse, it worked great.

Problems I'm having with my touchpad:

  • jumpy cursor
  • scrolling problems
  • Right-click panel shows by it self
    • when I scroll using 1 finger, the right click panel pops out by itself suddenly
  • Mouse lagging

Touchpad became unusable, it's totally not working properly anymore. It worked fine just an hour ago. It might be caused by an update I just did to ubuntu ? Ubuntu asked for an update an hour ago and after that the touchapd problem appeared.

Some Logs:

  • You could be suffering from This bug. Try booting another kernel version – boomt14 Apr 21 '16 at 21:14

Have you gone into System Settings and checked the values, its possible that they got changed by something in the update.

Also, try rebooting, I know this is the cure for a number of the other OS's problems, but every once in a while it works even in Linux.
