How to recover from freeze while nothing works?

Question

I am using Ubuntu 14.04.2 LTS. Sometimes Ubuntu freezes and i can't do anything anymore. What can i do to recover from this situation? In windows it was simple i just had to use task manager via alt+ctrl+delete. Is there something like this in Ubuntu? I know that there is xkill and System Monitor in Ubuntu but when Ubuntu freezes i can't use any of them and i can't open terminal and even though i have set a shortcut for xkill but still after freezing happens i can't use xkill. It's like after freezing nothing works.
