I was using Ubuntu 13.04 until a few days ago. I had installed Nemo and I guess cinnamon got installed too (I was still using Unity nonetheless).
One of the good things about that was the lock screen which somehow changed to mimick cinnamon's (with the background as a darkened version of desktop background and date/time displayed), something like this:
I have no idea how this happened, but it looked great.
It does not seem to work on Ubuntu 13.10. Anyone has any ideas to get a similar lock screen? I just need to display the date/time on one side with the backgroung as a darkened version of my desktop wallpaper.
