Press Ctrl-Alt-F2 and login with you username and password, Then:

journalctl -x --this-boot |grep -i lightdm

This is really weird. Maybe you can try Ctrl-Alt-F3 ？
Or, can you remember any operation done to your computer before this problem happens ?

When you upgrade something, you'd better check the detail of the list which shows the applications will be removed.
And try to check the log files under /var/log/ to get what it happened.

I have the same problem. When I click on Display icon, it does nothing. I am able to use the system but can not change anything with the display.
