Steps: 1. Install 14.04 + update (3.13.0-36), boot to desktop 2. Connect a HDMI / DP cable Expected result: * The external monitor should work Actual result: * The external monitor screen is black, and the Xorg crashed -> black screen on this laptop -> login screen shows up -> black screen... repeat. WORKAROUND: * Install the proprietary nvidia driver I'm not sure if this should be consider as a blocker. But hey, we need to certified this I+N system with the proprietary driver, I think it's OK to not to call this a blocker.
