I am having issues with nvidia drivers in 18.04. I am running Linux 5.0.0-37 on an i7 with GTX 1060 with stock Gnome desktop.
I am currently using the nouveau driver and am able to login and things are working okay, but if I try to install the nvidia drivers (any of the available ones: 390, 410, 415, 430, 435, 440), I am unable to successfully login to the gnome desktop, it just sits at a purple screen. To recover, I need to switch to terminal and purge the nvidia installs.
I see no errors in dmesg when I am unable to login. The nouveau driver works fine for general use, but I cannot play any of my Steam games with it. Any ideas on why all of the nvidia drivers would be causing this issue or how to troubleshoot?
