I am seeing this same bug. Albeit not on Ubuntu 11.10 but on Mint Linux 12, but I believe it to be the same. I am using a Lenovo B570 laptop which has a function key to increase and decrease the screen brightness. So in my case, once I enter the user password to unlock the screen, I then use the function key to increase and restore the screen brightness. This issue occurs regardless if I am running on AC or battery.

This makes it extremely difficult to see where someone should type their password to unlock the session. Additionally, brightness is not restored after unlocking the session either.
