I accidentally clicked the "guest" user profile and my system restarted itself, and now I can't get past a black screen with only the mouse pointer visible. Can somebody help me please?

Did you restart the system? – George Udosen Sep 30 '17 at 10:44

Do a boot recovery, enter fsck option and run it. Maybe some corrupted file. – Redbob Sep 30 '17 at 11:00

1Based on your description, in particular the part about how the mouse pointer is visible, I think Unity doesn't load, no Launcher, no Dash appears may help. – Eliah Kagan Sep 30 '17 at 12:09

- Press Ctrl+Alt+F1 and you will be taken to a command line terminal.
- Enter your user name and password to log in to your installed system.
- Type:
sudo systemctl stop lightdm - Type:
sudo systemctl start lightdm - You should now be taken to the Display Manager's login screen where you can select your session type and user account.
- In case you get lost, press Ctrl+Alt+F7 to be taken back to the graphical system
- If this does not work, if you manage to go past steps 1 and 2, run
rebootto reboot your system.

Few notes: Instead of using stop and start, the user can use
sudo systemctl restart lightdm. The required password is not the root one, but the user password. – Mostafa Ahangarha Sep 30 '17 at 15:58 -
Thanks, got mixed up a bit there and I corrected the response about the password. – marko Oct 01 '17 at 19:08
