I use the command lspci -vnnn | grep VGA and the output is
00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 18) (prog-if 00 [VGA controller])
01:00.0 VGA compatible controller [0300]: nVidia Corporation GT218 [GeForce 310M] [10de:0a70] (rev ff) (prog-if ff)
from this I can't understand whether nvidia graphic card is working or not. I was following a tutorial to switch it off but can't estimate it right now.
