I am posting for info:
I have been testing Ubuntu 14.04 on an ASUS G750JX for about two weeks. I have to say, it is a delight. This rig cost me an arm and a leg and came with Win 8.1. I was so unsatisfied with it that I almost sold it back. Then I decided to try Ubuntu Linux 14.04. Am I glad... It is speedy with graphics like I have never seen on Windows 8.1. The sound is crystal clear like I have never heard before when running on Win 8.1. Everything works but the keys to dim the display, keyboard brightness and sound (I guess no suprise there). However, you can dim the brightness and keyboard via the central command in gnome. I even have more battery time than I use to get in Windows. Here is the config:
Graphic: Nvidia Drivers 331.49 (Propriatory) - Unfortunately the nouveau drivers did not cut it.
If you don't have any obligations to be running Windows, get rid of it and try Linux on this specific rig and you will not be sad you did.
If I can be of any help, just let me know.
If you still need Window, you can just virtualize it like I did with Virtual Box .
A big thank you to the devs at Ubuntu & Gnome for developping such beautiful and streamline OS and Desktop Manager.
