Whilst attempting to download 16.04.1 it froze 3 hours in and was disrupted as I tried a PC restart. Upon rebooting I'm faced with the black screen in the picture: enter image description here I've no idea what my login is (if I ever had one) or how I can progress back to the desktop. Control Alt F1 or F3 gets nowhere. Any idea's

It's the same as your desktop credentials. Log in and reinitiate your window manager.

To restart the WM on Vanilla Ubuntu 16.04, once you've logged in of course:

  1. sudo service sddm restart
  2. nohup unity --restart

If your machine is stuck on 14.04:

sudo service lightdm restart

  • just a note, the user asking the question appears to be rather new, judging by their rep, so you should likely include the commands to restart it. sudo service sddm restart nohup unity --restart – Zalgo Aug 11 '16 at 18:02
  • Yeap, you're right - my fault. I can't comment yet to ask him what Window Manager he was using but some general direction would certainly be of help. – Matt O. Aug 11 '16 at 18:04

    What about sudo service lightdm restart? – You'reAGitForNotUsingGit Aug 11 '16 at 18:09
  • Zalgo's solution works on Ubuntu 16 while I believe LightDM is for 14.04, so both should be included. Correct me if I'm wrong. – Matt O. Aug 11 '16 at 18:21
  • None of the above commands make any difference. Its been suggested that I've broken the configuration as the computer was restarted mid update. – Paul Thomas Aug 12 '16 at 12:24
  • At this point I'd suggest moving sensitive files to a flash drive and reinstalling. Ubuntu (and every other OS) makes the recommendation to backup before upgrades. There's have been more than a few botched upgrades lately. That said, build a bootable USB and reinstall. If you need some direction for that checkout Linux Live USB Creator. It's always worked for me. – Matt O. Aug 12 '16 at 14:51
