A black screen with an X is the Xorg server running without a shell, so
gnome-shell probably crashed. Please follow these steps:
1. Run these commands:
journalctl -b0 > journal.txt
journalctl -b-1 > prevjournal.txt
and attach the resulting text files here.
2. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
3. If step 2 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.
Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.
