I fresh installed Ubuntu 14.04 on my new laptop and I'm struggling with the graphic card.
I have an integrated Intel card + an NVIDIA GTX 860M coupled with optimus technology.
I understand that optimus is a big source of problem with linux and I tried several of the proposed solutions to make my NVIDIA work. Neither bumblebee nor nvidia prime seem to work. Ubuntu recognize only the Intel card:
lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
PS: Need more information, Ask me
PPS: Sorry, as English is not my native language
