There is no optimus, so the graphics work great off the bat. Only one visible issue is that the USB 3.0 ports all around the laptop have an issue where they may or may not work. If they don't work, usually a restart will fix it. When they don't work, no usb device will be recognized (ext. HDD, mouse etc).
Everything else seems to work off the bat. Most importantly, the Qualcomm Atheros Wifi works and the bluetooth work. The BlueRay disc drive works great as well. No issues with EUFI at all. Speakers work great and loud. Nothing special was done, just a fresh install and getting the 331.38 Nvidia drivers from Additional Drivers.
Here are some pictures of Ubuntu 14.04 running on the Asus G750JX laptop (notebook).
