# Ubuntu – VirtualBox crashes Ubuntu 16.04 vm’s

Ubuntuvirtual machinevirtualbox

Host: xubuntu 16.04 amd64
Guests: xubuntu 16.04 and lubuntu 16.04

The vm crash right away when booting for the very first time from the desktop iso's. The screen gets garbled. And that's it. The picture shows the xubuntu 16.04 screen. Lubuntu's 16.04 looks evenly strange.

Lubuntu lets me select a language. Xubuntu crashes after the dot animation. xubuntu 15.10 seems to install properly.

Is this a known problem?

Forgot to mention this is VirtualBox 5.0.18_Ubuntu r106667.

• Not really a solution, but to work around the problem, you have to issue the guest OS Ctrl+Alt+F2 followed by Ctrl+Alt+F7. This will cycle through the TTY and back to X11, therefore restoring resolution to the correct value. In order to issue the Ctrl+Alt+FX combo you should press Host_key+FX. (Host_key is by default mapped to the Right Ctrl key in VirtualBox). Oracle seems to consider this a bug in Ubuntu, and therefore will not try to solve it.
