How well do laptops with Nvidia Optimus work?
I have a Lenovo Z580 (12.10 Quantal). It has both an Intel HD 4000 and an NVIDIA GT 630M (CUDA and Optimus).
When using Ubuntu, my laptop battery runs out much quicker than on Windows and the laptop also heats up more than on Windows. Is that because Ubuntu is using the NVIDIA card all the time?
I don't have any driver installed for the card. I tried
apt-get install nvidia-current to get the proper driver but it caused many problems. (Resolution stuck on 640 x 480, taskbar and launcher not appearing, only background shows, i used ctrl + alt +t to open a terminal and remove nvidia current)
Do I need to install proper drivers (or Bumblebee)? Will it help my battery life?
