First of all, don't judge me instantly, this might seem like duplicated question but honestly, I can't find solution to my case. That's why I came here.

Okey here's the deal. I started my morning by starting my computer and log in to Ubuntu. Everything worked like a charm! Then, just like time to time, system updater popped up and there were couple updates. I checked them, and everything looked great and then I clicked "install" or "update" - for some reason not sure what that button says, but anyway... Then, meanwhile I was finishing my coffee, the updates finished and I decided to start my workday. At the moment I'm working on with big video project so I opened kdenlive. But unexpectedly it doesn't opened at all, and kdenlive wasn't only one whom behavior was weird. So I was still bit sleepy so I haven't enough energy to start figuring out what's going on so I decided restart computer and crossed my fingers that it would be magic reboot. Well.. it wasn't.

Login loop decided to stopped by. First reaction was, oh sh*t is my system broken? Did I lost everything?

I guess I didn't. I assuming I could fix this if I'd be able to open TTY. ctrl + alt + f1 give me black screen. I followd this answer: Graphics issues after/while installing Ubuntu 16.04/16.10 with NVIDIA graphics

and I edit my GRUB and I placed nouveau.modeset=0 in there and reboot my system but no luck.

After couple of hours I figured that TTY is the only way how I can get this working again, right? Do you have any suggestion how could I open my TTY and get rid of the login loop? I really appreciate every reply.

Thank you!

EDIT When I place nouveau.modeset=0 in GRUB and reboot, this come: /dev/sda8:clean, 412123/3055616 files, 2982833/12207104 blocks

when this is on the screen, I'm unable to type anything and after couple seconds the normal login screen appear and I'm still unable to open TTY.

Ctrl + Alt + F2 to get to a terminal. Login then shut down the graphic interface:

sudo service lightdm stop

Then update:

sudo apt-get update

then get rid of all nvidia stuff:

sudo apt-get purge nvidia-*

then try:

sudo apt-get install nvidia-340

Then

sudo reboot

Hope that helps! This is just a from-memory suggestion on similar issues I've had.
