I have just done a clean Ubuntu 16.04 LTS install on my MSI GS40 Phantom 6QE, ive got the dual harddrives connected and all of the graphics look fine while using the stock Xorg drivers and i dont have any problems anywhere, but I might want to do some gaming later and I have got a GTX 970M graphics card so why not get it running right?

I had a problem running in legacy mode with the nvidia-641 drivers giving me the login loop so I re-installed in UEFI to hard set my secure boot to disabled.

Now I am both, curious to see if the drivers cause the same problem in UEFI with sec boot off, and prepared to fix the problem again if i get the login loop again.

Here's the problem, when I run:

sudo apt-get install

I can pull down the nvidia drivers but i cant get access to nvidia-364, which everyone says is the fix to the login loop issue.

When I run:

sudo add-apt-repository ppa:graphics-drivers/ppa

I get an error stating that the PPA is unknown. I am seeing that if I add this PPA I can fix the loop error with the newer drivers, so does anyone know about this ppa error?

  • Have you run sudo apt-get update and sudo apt-get upgrade yet? That PPA looks correct, and works on my 16.04 machine. – TheWanderer Aug 4 '16 at 0:58

By using the proprietary intel driver and then running

sudo apt-get update


sudo apt-get-upgrade

after enableing the intel driver, i was able to add the repository, but the nvidia-364 driver still threw an error though when i tried to install using

apt-get install

so i ran apt-get update / upgrade again and was able to install nvidia-364.

logged out and was able to log in, loop resolved

update: double checked that nvidia-364 binary driver was installed and running, full shut down, still no login loop

  • I'll delete my answer. You deserve the reputation. – fosslinux Aug 4 '16 at 2:23
  • command sudo apt-get-upgrade not found – toing_toing May 18 '18 at 14:16
  • probably he meant sudo apt-get upgrade – markroxor Jul 30 '18 at 7:24
