=== Issues with Ubuntu in VirtualBox ====


Restoring the VM after it was saved freezes Ubuntu. Resizing the VM windows helps to resolve the issue: [[https://www.virtualbox.org/ticket/13487|VirtualBox Ticket #13487: Ubuntu Desktop 14.04.1 freezes when restarting from saved state (3D)]]

myuser@myserver:/home/myuser$
</code>
