I have just installed ubuntu 18.04 LTS on my Assus 556-UX notebook with Nvidia 930MX card. I have noticed that in the 'details' section in 'Settings' it still says the graphic card is the intel's on-board card, so I wanted to install the nvidia driver. I am new to linux, what is the best way of doing this?

thank you

I usually install the Nvidia drivers from the terminal:

$ sudo apt-add-repository ppa:graphics-drivers
$ sudo apt update
$ sudo ubuntu-drivers autoinstall

(then reboot)

You should be able to switch between your Nvidia dGPU and Intel iGPU using:

$ sudo prime-select [nvidia|intel]

You can query which GPU is in use using:

$ prime-select query

NOTE: I have had huge headaches with Nvidia drivers lately, namely:

  • The Nvidia GPU doesn't power down after switching to the Intel iGPU.
  • Lots and lots of "micro-stutter" when scrolling/dragging windows.

I found a "fix" (workaround?) for my particular laptop in regards to the first issue:

  • Edit /etc/default/grub after switching to the iGPU.
  • Find the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.pm=1"
  • Remove the nouveau.pm=1
  • From the terminal, run: $ sudo update-grub

I haven't been able to find a fix for the "micro-stutters", but this issue is subjective and will bother some users more than others (I'm in the former group, it bothers me a lot - so much so that I have uninstalled the proprietary Nvidia drivers and am currently using the Nouveau drivers, which are much "smoother" for most desktop functions).
