I installed Ubuntu 16.04.1 on VirtualBox. I logged in, installed VirtualBox additions and restarted the system. The system did not load again, instead I see this:

The aspect ratio of the image is preserved in this screenshot and it doesn't make much sense to me - no screen has such dimensions. I did not do anything else special that I could mention. This is the only thing I see before the screenshot above:

As memory serves me, switching TTY's should fix the problem.

In your case, I can't see what your HOST key is set for, so please take note. To fix your video problem, hit the host_key + F1, followed by host_key + F7. It's a bug.

On a Mac, you may have to host_key + fn + F1 and then host_key + fn + F7

For the journal errors... check your file system...

  • boot to the GRUB menu
  • choose Advanced Options
  • choose Recovery mode
  • choose Root access
  • at the # prompt, type sudo fsck -f / (or sudo fsck -f /dev/sda1)
  • repeat the fsck command if there were errors
  • type reboot

  • It fixed the problem, but could you explain what happened? – Tomáš Zato Feb 08 '17 at 16:16
  • The video problem is a long standing bug. The journal problem was some disk corruption. – heynnema Feb 08 '17 at 16:17
  • And what does the F1/F7 combo do? – Tomáš Zato Feb 08 '17 at 16:18

    Ubuntu has 6 text terminals, and one (or more) graphic terminals. My commands force a switch to the first text terminal, and then a switch back to the graphic terminal. It works around the bug. You may never see the problem again, or if you do, now you know how to get around it. – heynnema Feb 08 '17 at 16:20
