This question already has an answer here:
It seems infinite login is a Ubuntu 16.04 problem. There is no infinite login on Xubuntu 16.04, but I will encounter Nvidia card problem described below.
I also tried Ubuntu 17.10. Ubuntu 17.10 actually can detect my Nvidia card. However after installing the driver, whenever I boot my machine, it will get stuck on loading, with black screen flickering.
I described in my answer that I switched to use Xubuntu 16.04. I managed to install Nvidia driver through PPA, and I did not get stuck on the log in screen. I have set secure boot to off. I now switch to use a proprietary driver. This way I can open Nvidia settings, but Nvidia settings does not list any GPUs.
However, something is still wrong with my graphics card.

In Software & Updates the graphic card is unknown:
With PPA installed open source Nvidia drivers, when run
Xlib: extension "GLX" missing on display ":0.0". ERROR: Unable to load info from any available system
At this point, I cannot:
- change brightness either through function keys or through apps,
- detect or extend to second monitor

I know that this may have been asked numerous times, but none of the solutions I found online worked.
I am running a new XPS 15 9560 with GTX 1080. I installed the Ubuntu 16.04 today, following this instruction .
In particular, I followed the above instruction to use PPA to install a Nvidia graphics driver. I also disabled secure boot on my machine. I got into an infinite login loop no matter which driver I use. I can manage to get out of the login loop by uninstalling the driver. I could not get the Nvidia driver to work no matter how.
I have looked at
line 1: Xlib:: command not found line 2: Xlib:: command not found line 3: openConnection:: command not found line 4: cannot: command not found line 5: syntax error near unexpected token '(' line 5: 'upstart: gnome-session (Unity) main process (1497) terminated with status 1
I have also tried the method mentioned in this post: Ubuntu gets stuck in a login loop. I did have
-rw------- 1 root root 53 Nov 29 10:19 .Xauthority drwxrwxrwt 15 root root 4096 Nov 30 04:17 /tmp.
However changing ownership (
.ICEauthority did not help. I cannot login to either of my account or the guest account.
