The touch pad occasionally freezes on my laptop. If I plug in a USB mouse I can move the cursor but the touch pad remains frozen until after I restart. I am running Ubuntu 14.04.

  • Check dmesg | grep psmouse. Is 'psmouse' driver actually running? This can be delayed (for reasons unknown) for up to 8-10 minutes. Something to do with power-saving and Windows. Are you also running Windows on the PC, or have you recently?
