I know there are multiple threads on login freeze and the fixes that I found require the user to run shell and download some drivers. My problem is that I can't open the shell because either the freeze happens before I even try to log in, or, if it doesn't happen instantly, then none of the key combinations work for me. I tried Ctrl + Alt + F1-F6, and tried Ctrl + Alt + Fn + F1-F6 as well. Nothing happens. And then the freeze happens. I would appreciate any hints because I'm at a loss as to what to do now.
I've got a Dell Inspiron 7567 i7-7700HQ with NVIDIA GeForce GTX 1050Ti graphic card. I have a Windows 10 installed and have just completed my Ubuntu 18.04.2 installation alongside Windows.
