Ubuntu – How am I supposed to use nvidia-prime

nvidianvidia-optimusnvidia-prime

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 nvidia-prime with

sudo apt-get install nvidia-prime

What am I supposed to do now?

I thought 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?

Best Answer

You need to have both Nvidia proprietary drivers and nvidia-prime to get it working. This can be done by running

sudo apt-get install nvidia-346 nvidia-prime

for Ubuntu 14.04 and 15.04.

Then you will have Nvidia X Server Settings in Dash. And there you can find PRIME profiles.
