Bryce, first off, sorry for mistyping your name ;)

I did a bit more testing, and I tried the classic/no effects login again. If I start undocked and dock, I do get the black screen/responsive mouse pointer. However, if I log in with classic/no effects *and* do "xrandr --output LVDS1 --off" and then dock, one monitor lights up with a real desktop (ie it seems to work). The second monitor was off, but I was able to get it to light back up by going to a text console and back to X. (I guess this is the second conflating bug you mentioned).

I tried a standard unity login and did the "xrandr --output LVDS1 --off" and I still ended up with a black but on monitor.
