I got my Linux Mint 16 into this same state without ever touching aptitude or mongodb. It seemed to occur after some regular updates, I don't do anything out of the ordinary with my Mint install, but when I logged back in I got the blank screen with the "LM" icon floating in the middle. I can ALT-LEFT and get to terminal, run "sudo mdm", and get to the login screen, however immediately after logging in I get "Session Failed" with a detailed error message:
"cinnamon-session-cinnamon" not found; falling back to default session. localuser:jyennaco being added to access control list Script for cjkv started at run_im. Script for default started at run_im.

I saw another forum where someone had these same 2 seemingly different problems) Naturally form the terminal I ran: sudo apt-get --purge remove cinnamon && sudo apt-get install cinnamon sudo apt-get install cinnamon-screensaver sudo apt-get install nemo After rebooting I was able to log in using "sudo mdm" and logging in, I was got to my desktop! However, cinnamon still does not start on a normal boot without sudo mdm. Please advise!
