updated, then restarted and now the touchpad is not useful
it converted into a vertical and horizontal scrollwheel, all the surface
i'm posting this from the livecd
i found a post made by Texstar talking about some fixes but not sure which one could help on this case
If it was me, I would start with Solution 1 and if that did not work I would try Solution 2. Or start with Solution 2 and then try Solution 1. or copy the file from the LiveCD which is Solution 2. to the hard drive install.
