I'm experiencing an issue where, after booting a MacBookAir4-2 (Ubuntu 13.04), the touchpad won't work. Furthermore, the better part of the keyboard doesn't work either. External USB keyboards and mouses work, and I have to use them to disable and re-enable the trackpad in the settings to get the on-laptop one to work, which also enables the keyboard for some reason.
I do not experience any issues during the reFIND menu or in OS X. Is there a way to fix this or a script that I can run at startup that can enable and disable the touchpad?
