Thanks for your bug report. I gave this a shot on my x220. Upon logging out, my screen is black for maybe half a second, but redraws after that, which might just be normal behavior. I don't have a custom image for my login screen, in the event that ends up being relevant. In any case I'll open a task against xorg. Could you please run "apport-collect 909176" in a terminal? That'll add some detailed system information to this bug report
