I have the same model cf computer, but with different graphics hardware - the Asus G750JM-T4019D Full HD, Haswell i7 4700HQ, 8GB, 1TB, nVIDIA GeForce GTX 860M 2GB.
I am successfully running Ubuntu 14.04 Gnome, but I didn't try to install any special driver during initial installation. I just let Ubuntu install its default drivers. My system is running quite stably and without problem, although I'm * probably * not getting ALL the functionality I possibly could if I had a driver specific to my system.
I read your thread at https://devtalk.nvidia.com/default/topic/771674/linux/ubuntu-freezes-at-login-with-the-gtx860ms-official-drivers-installed-/
As far as I could understand, you opted to install special Nvidia drivers during your initial installation process.If I'm not mistaken about this, I'd recommend not doing so, and just using the Ubuntu 'default' driver.
Hope this helps.
