Ubuntu randomly started blinking the screen on boot
I used my Ubuntu Desktop yesterday as usual, but now I can't boot in because the screen keeps flickering to a black screen and a verbose boot screen where I see no failure or errors. I can ALT-F2 and see the login, but it stills flickers so I can't type correctly my password. I didn't install anything particular, I've searched a little and people talk about NVIDIA drivers, but I didn't install anything like this yesterday, what can I do?
Thanks for helping.
dpkg -l *nvidia* | grep ii returns
nvidia-375 375.66-0ubuntu0.16.04.1
nvidia-opencl-icd-375 375.66-0ubuntu0.16.04.1
nvidia-prime 0.8.2

Uninstall the Windows driver that allows you to read/write to Ubuntu EXT4 partitions.
-
To check the file system on your Ubuntu partition...
- boot to the GRUB menu
- choose Advanced Options
- choose Recovery mode
- choose Root access
- at the # prompt, type
sudo fsck -f / - repeat the fsck command if there were errors
- type
reboot
Update #1:
- boot to the GRUB menu
- select Ubuntu
- hit the e key
- use arrow keys to move
- find the line that has "quiet splash"
- add
nomodeset, so "quiet splash nomodeset" - hit F10 to exit and continue boot
- see if it flickers
I recently had the blinking screen on a dual boot Ubuntu 18 and Windows 10 machine and the boot sequence seemed to be stuck. When I tried CTRL+ALT+DEL a message was displayed that unattended updates was in progress. At some point the blinking stopped and a finished message appeared. The machine rebooted, and everything was normal after that.
