The touchpad on my MacBook Pro (7, 1) running Ubuntu 12.04 64 bit has stopped working. It worked fine on the initial install of the operating system but after an instance of the laptop running out of power, the touchpad stopped working. I ended up reinstalling the operating system. The touchpad began working again. Unhappily, when the laptop again ran out of power, the touchpad again stopped working! Do you have any idea why this may be happening? I don't want to reinstall the operating system every time I run out of power! Thanks for any suggestions.
