I've had this laptop for about a month and the touchpad (ETPS/2 Elantech Touchpad) was working fine. Yesterday that changed. I had this weird issue with my battery where it didn't recognize that I even had a battery (acpitool said battery: "not available") and therefore it would turn off right when I unplugged the charger, as if it were a desktop computer and not a portable laptop with a rechargeable battery. Anyway, after one of these shutdowns my touchpad stopped working. Now the battery is working fine but the touchpad is not. I checked out all of the similar questions on this site but none of them worked or matched my circumstances. Here are the details:

  • No X11 cursor shows up.
  • I'm running debian jessie with kernel 3.16.0-4-amd64.
  • My touchpad is both recognized and enabled
  • my synaptic touchpad package is fully updated
  • xev shows no response from any interaction with the touchpad
  • a usb mouse works, which I'm using right now
  • I don't have an xorg.conf

Thanks all. I'll add anything that will help if asked. I cannot figure out what could be causing this.

The answer is I am a dumbass. Sorry all. Apparently there's a keyboard shortcut that does it to the firmware. This is why I can't have nice things.
