My touchpad is no longer working. Here is what I get when I do not have an external mouse plugged in:

$ sudo xinput list
[sudo] password for gwlester:

  • As suggested, did: sudo modprobe -r psmouse # PS/2 mouse driver sudo modprobe psmouse proto=imps # Add proto=imps option No errors but no effect.

Some diagnostics would be helpful.

  1. Does the touchpad work when running from a Live Ubuntu USB? If so, you know the cause is with the installed system; if not, the cause is hardware.
  2. What occurred before this issue? Ubuntu update? Power failure? Spilled coffee? Something else?
  3. Have you shut down and rebooted?
  4. In the Synaptic Package Manager, have you checked status of packages? Tried Edit | Fix Broken Packages?
  5. Have you tried fixing broken packages from Terminal?

  • 1) Downloading Live and will attempt to run and report results. 2) Stopped working after an upgrade. Finally got annoyed enough to fix. 3) Many, many, many times. 4) Yes, shows no broken packages. 5) Yes, shows nothing wrong.

  • You state, "Stopped working after an upgrade." That important bit of data should have been in the question, which would have led to an obvious suggestion: back out the upgraded packages. Of course, by now, there will have been other upgrades, making it more difficult to identify the culprit(s).
