Btw, the other even more odd workaround: switch to text console, kill gnome-terminal and switch back to the VT used by X, and you can unlock then.

If I use CTRL-ALT-L to lock my session, it normally works as expected. However if there is a fullscreen gnome- terminal (F11) was on the screen, CTRL-ALT-L does something interesting: it begins fade the screen but it's left in a middle state, no way to unlock but also it's not locked visually though I can't type anymore. More interestingly: it seems the screen IS locked, since if I type my password "blindly" (I still see the half faded session ...) I get back my desktop in a usable state! Interesting.
