I have an acer laptop with these GPUs:
– GPU0: Intel HD Graphics 4000 (M) (obviously integrated)
– GPU1: NVIDIA GeForce GT 710M
I uninstalled all nvidia-drivers because I was experiencing a lot of bugs and I read here and there that they are not supposed to work with Optimus without either bumblebee or nvidia-prime.
As far as I understand, nvidia-prime would allow me to have the NVidia GPU always on. And to choose between that or always off (i.e. always use Intel)
So now I installed
sudo apt-get install nvidia-prime
What am I supposed to do now?
nvidia-prime provided a graphical interface which would allow me to choose which graphic card to use, and even to install the needed nvidia drivers.
By typing "nvidia" in the dash, nothing shows up.
From a terminal, the only command available starting with "nvidia" is "nvidia-detect" which just prints "none".
So, I installed nvidia-prime, how do I use it?
