I'm having this issue on both precise and raring on ThinkPad X201. This issue only appears when external display attached to DisplayPort.
The behavior is consistent with stock/mainline kernel with stock or intel linuxgraphics drivers (3.8.0-26-generic, 3.8.0-27-generic, 3.8.0-27-generic with intel linux-graphics 2013Q2, 3.10.0-997-generic,3.10.0-997-generic with intel linux-graphics 2013Q2). External display works perfectly on VGA port.
