An external monitor connected will work fine. This setup works fine in previous versions of Ubuntu. (Previous versions need the 'noapic' flag to boot though). Someone else reported similar problems on a Thinkpad L520, and also saw it on Ubuntu 11.10 with the vanilla 3.2.0 kernel compiled from kernel.org source. They worked around it by disabling modesetting in grub.
