At some point in the last week, my touchpad stopped working. I say "some point" because I normally use a mouse, except once a week, when I use the touchpad.

In the settings GUI, I no longer even have a touchpad tab.

How can I get this working again? I guess the first step is determining what I have. But I don't think this command tells me much.

Do I need to reboot and go into my BIOS?

You should update your answer to provide more information, like your Ubuntu version and architecture. Also check if you get any output from grep -i Touchpad /var/log/Xorg.0.log.old that could help diagnose your problem. – Salem Feb 20 '13 at 11:39
