Here is what I found worked for me :
cinnammon --replace --clutter-display=:0 2> /dev/null &
- :0 is my screeen (use command
wif 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.
