Have you entered to the graphical session from the recovery mode with the command startx?
Once being "tinkering" suddenly closed Cinnamon and left a message (Cinnamon just crashed. You are currently running in Fallback Mode.) And the graphic session opened in Gnome-fallback mode (much like the old Gnome2 interface) . Whether logged off and restarted the pc even if the same thing happens again, the error message came out and fallback Gnome-opened.
From the Gnome-fallback interface I changed the name of the directory / home / user / .config, another name: / home / user / .config_b. I closed the session and went back inside, this time if I could enter and Cinnamon .... I saw that they had created a new / home / user / .config almost directories inside, creating as it would again use the programs. That if I had to go back and reconfigure the Cinnamon panel, activating applets / extensions you want from among those who had installed, and reconfigure some extent as Cinnadock. That had already practically new system as it had before the disaster.
Once again had to set my taste Cinnamon made a backup of / home / user / .config and later, on another occasion I had the same problem solved by deleting the / home / user / .config problems and replacing by the backup.
From this I have concluded that various other configurations of Cinnamon to those discussed above are stored in subfolders of the directory / home / user / .config
