Practically everything, including the graphics card.
Note the specs please, I have heard of problems when there is an integrated graphics chip (ie Core-i5s) and the nVidia driver. Suggest you should buy a Core-i7
|What doesn't work:|
Two of the touch buttons are read by the system as brightness up and next song (one is user configurable).
Cheese will not record video from the webcam.
TV Tuner doesn't work
|What was done to make it work:|
Had to install using the USB 2.0/eSATA port instead of the USB 3.0 ones, it could not access the files if the USB installer was plugged into the USB 3.0 ports.
Had to download a fix for the touchpad to enable two fingered scrolling. - UPDATE - THIS IS NOW WORKING BY DEFAULT IN UBUNTU 11.04
Have not found a driver to support gestures using the touchpad yet.
Intel Core i7-740
