Public bug reported: My computer runs very slow if I have a second monitor connected when I boot. The slowdown occurs after the logon screen (which is fine). After trying to find the problem, I noticed that if I boot with only the laptop screen on and connect the 2nd monitor once Unity is loaded, everything runs fine. The slowdown makes it hard to extract diagnostics (or do anything for that matter).
I only use one monitor on at a time.
