I have a couple of VirtualBox ubuntu VMs with Guest Additions installed: 16.04, 16.10, 17.10, all of them work fine prior to upgrade. In fact, I just did a do-release-upgrade yesterday from 16.10 to 17.10 and everything works fine.

Today, seeing that 18.04 LTS has been released, I upgraded two of my 17.10, and both of them failed to boot after upgrade. They flash 4 times between the small verbose boot sequence screen and a full screen black screen before freezing. Both of them have very similar failure.

Ubuntu 18.04 LTS failed to boot after upgrade. Started Display Manger.... link was shut down..

Ubuntu 18.04 LTS failed to boot after upgrade. Started GNOME Display Manger... kernel crash signatures....as shut down..

I attempted to hold shift during boot to enter recovery and command prompt to

sudo apt-get remove virtualbox-*

but the problem persists.

My host is 64-bit Windows 7 Ultimate on a Z77 platform with a nVidia GTX 750 Ti graphics card. VirtualBox version 5.2.8 r121009 with Extension Pack installed.


My machines were able to boot normally after disabling 3D Acceleration in VirtualBox.

Settings > Display > Screen > Acceleration > Enable 3D Acceleration (Uncheck)

Disable 3D Acceleration in VirtualBox

An alternative fix is welcome because I had been using 3D Acceleration fine since forever so I do not understand why it has to be disabled, or if it is really the culprit. Since the feature was working before 18.04 I suspect it to be a new bug unrelated to previous issues.

  • I get the same errors on bare metal, is there a way to do this within the guest system? – Gabor May 9 '18 at 3:03
