@ Luiz okay! I will keep ubuntu 10.04 for a while, a week, perhaps. Like I said, when I (re)moved the file, and restart, the driver started: ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ PS/2 Mouse id=13 [slave pointer (2)] ⎜ ↳ AlpsPS/2 ALPS GlidePoint id=14 [slave pointer (2)] My laptop don't freeze because of the Ivybridge, i'm using https://github.com/Bumblebee-Project/Bumblebee, it looks good, but some webgl don't work, but it's okay!
