I have a Asus with 2 graph cards - 1 nVidia and 1 Intel - and my battery life is being shortened because I THINK both gpu are being used by Ubuntu. I tried some called Bumblebee but or I configured it wrong or it didn't work.
Any idea on how to do this? I've seen other posts but none of them worked. Sorry for any mistake but english is not my main language.
PC : Specs
Ubuntu version : 14.04
[UPDATE] So I followed what was suggest in this question in an answer and everything went well. I can't run optirun for some reason ( it never detects my secondary GPU ) and so I'm still working on that.
Battery life is at 1h40min .
