I have confirmed that this bug also affects Lubuntu 16.04.1 (32-bit) running under VirtualBox 5.1 (the latest version, at the time of writing.)
The workaround also works: switching to a text console. Others report that it did NOT happen with the original release 16.04. ** Bug watch added: Virtualbox Trac #13615 http://www.virtualbox.org/ticket/13615 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1379062 Title: Graphics problem in Virtualbox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1379062/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
