Hello,
After 6 mounts of testing distros for my Optimus laptop I have finally found one: Ubuntu MATE.
I really would like to give a big Thank to all Devs.
With some tweaks and learning this is the only distro that works for my needs and didn't make me think to reboot to win8.1.
Thank very you much again!
PS: With nvidia 396.54 it boots way faster
