After updating to Ubuntu 18.04 lts I see a black screen with a cursor, how can I fix it?

Question

linux

Problem in the graphical shell or already need to reinstall?

Answer 1

Ctrl-Alt-F1 go to the console terminal (graphics usually starts on the seventh terminal go to Ctrl-Alt-F7), there will be a user login prompt.
log in - find out what's wrong
start with "journalctl -b 0" last boot log. see what happened.

Answer 2

And besides the cursor, is there anything else that is output to the console? What was before the update? I usually save application settings in the cloud and rearrange the system completely.

Answer 3

I have the same problem. What to do. Reinstall everything and not suffer?

Answer 4

If the drivers are proprietary, rebuild the dkms module.
It may well be that the installation of the packages was not completed, then:
sudo dpkg --configure -a
