Here is what I found worked for me :

cinnammon --replace --clutter-display=:0 2> /dev/null &

• :0 is my screeen (use command w if you need to find it)
• & give me back the terminal when done
• 2> /dev/null sends results to the bin
• –clutter-display Use current user session screen. Otherwise the "current screen" is used, wich might not be what you want when you 're ina TTY session trying to recover from a crash / freeze.

And it did save my day. Saved my day.
