RAM yes
or maybe swap.

But CPU?


if the process has nothing to do - and waiting for input, without even being displayed is a very good definition for 'nothing to do' it needs no CPU. It is just waiting for the moment, it get back on display and has to react to some mouse/keyboard events.

You can freeze the other session, in fact, if the other session does nothing than waiting for input, so does not load websites, plays videos or music, it will have no impact.

By the way, you can freeze it in the real way: sigstop.
But that is not needed.
