Some time ago I wrote a guide concerning the cards Optimus di NVIDIA, and that is su how to install Bumblebee, which manages the switch between the integrated card and the dedicated card.
I also briefly described how to update the drivers once Bumblebee is installed, but today I want to write a more detailed guide, so let's go straight to the guide.
First you need to add the repositories, then update:
sudo apt-add-repository ppa: xorg-edgers / ppa sudo apt-get update && sudo apt-get upgrade
And immediately after we can install the drivers if you have already installed Bumblebee, otherwise follow the guide linked in the first part to install it
sudo apt-get install nvidia-331 nvidia-settings-331
This command will install the current version. If the driver version is different, just change the number.
Without this, all that remains is to modify the bumblebee configuration file, bumblebee.conf
sudo nano /etc/bumblebee/bumblebee.conf
Of course you can also use a text editor instead of dwarf, for example gedit o kate (depending on your distribution), so you can use a graphical interface. Here you need to change a few lines to get the following:
|line 22||Driver = nvidia|
|line 55||KernelDriver = nvidia-331|
|line 58||LibraryPath = / usr / lib / nvidia-331: / usr / lib32 / nvidia-331|
|line 61||XorgModulePath = / usr / lib / nvidia-331 / xorg, / usr / lib / xorg / modules|
All that remains is to update bbswitch and restart bumblebee
sudo apt-get install --reinstall bbswitch-dkms sudo /etc/init.d/bumblebeed stop sudo /etc/init.d/bumblebeed start
To check now the difference of framerate per second between the integrated Intel card and the dedicated NVIDIA card, let's move into the folder / Opt / VirtualGL / bin
cd / opt / VirtualGL / bin
to check the integrated video card;
to test, instead, the fps and Megapixel / s of the dedicated card.
