The external monitor not working from the Intel GPU is not a bug, it's expected due to the display not being physically connected to the Intel GPU. It *should* work in Discrete mode however, and I'm marking this bug as a duplicate of the T520 Discrete mode hang bug. It's likely the same cause. *** This bug has been marked as a duplicate of bug 835648 ***
