Basically, vga cannot detect NVIDIA cards as "VGA compatible
controller", this is tested on a Optimus System.

dmesg indicates that it's not a valid vga device:

:~$ dmesg | grep vgaar
[    0.202410] vgaarb: device added: PCI:0000:00:02.0,decodes=io+mem,owns=io+mem,locks=none

According to this:

it's look like the patch for vgaarb is not in 14.10
