here's the documentation on all of the suspend states:

So "Freeze" means "Suspend to Idle", which is the only power saving
state
available that does not require hardware cooperation. It will give you
the absolute lowest amount of power saving available, and in most cases
won't even be worth the trouble of having to reconnect network services,
etc. when you bring the machine back out of Freeze.

Thank you Tim for the explanation. Interrestingly, TDE on openSUSE has both
suspend to disc and suspend to RAM (and both work, even if the machine seems
stuck a while when comming out of suspend to disc), but TDE on Ubuntu proses
suspend to RAM and Freeze.
