My NVidia GTX 960 card creates openGL problems with Unity on Ubuntu
Solution 1:
Don't worry about the lspci part. It's just because your /usr/share/misc/pci.ids* files are not up to date. Just run "update-pciids" as root.
Before running update-pciids:
$ lspci | grep GeForce
$
Running update-pciids:
$ sudo update-pciids

01:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1)
I'm using NVIDIA's original 346.59 drivers (last stable as of today) without problems in 14.04.
