When using a multiple monitor setup (not mirrored), the login dialog for unlocking a locked desktop may not always be visible. (You may see a flash of a dialog before it is obscured by the backdrop.)

Workaround: I was able to type my login password blindly, however, without seeing the dialog, to unlock the screen. I then disabled multi monitor for now. I am aware that there are other outstanding issues to be resolved with the drivers anyway. With my primary monitor only, the dialog is visible.

The main monitor, 1920x1080, is a 23" 16:9 Viewsonic VP2365wb on VGA input.

The secondary monitor, 1024 x 768 20" Envision EN2028 on VGA input. (Note that the second monitor on my system is listed as "unknown" by both Ubuntu and Mint, however several other distros with the unstable debian kernel recognize it, and allow me to set different resolutions on it as well.)
