I'm in a HP 430 PC-Notebook using Oneiric. And sometimes my touchpad just stop working :(... I haven't installed anything, just safe playing with terminal following linuxcommand.org BTW my touchpad has a "hole" that in Windows, it works like this: two touch, block touchpad, two touch, unblock. And as far as I now, Ubuntu hasn't recognize this function so I think that the "hole" is not the problem... Also, I'm pretty sure that I haven't touch a little that... PD: Spanish speaker, sorry if "hole" is not the appropriate term haha.. Thanks!
