Ubuntu: Ubuntu in VirtualBox does not start after restart and shows weird pixelated screen


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
