Ciao Michele,
I tried it out. Both "Freeze" and "Suspend" work! It rocks!
I have another question, also tangential to TDE. I am still using the default SDDM that
openSUSE Leap 15.2 came with as
the login display manager. It has no "Hibernate" button, but it has a
"Sleep" button. Any idea whether this corresponds
to Suspend (to RAM) or Hibernate? Last time I tried it out it made my laptop hang but
that's before I fixed the problems
with Hibernate (had to switch from "platform" to "shutdown"), so it
makes me think that "Sleep" in SDDM is actually
Hibernate (or something obscure). But this is irrelevant to everyday use since I normally
just hibernate from TDE.
I also noticed an interesting fact about "Freeze". If you logged in remotely
into the laptop and you put it into the
"Freeze" state, your login shell is also "frozen" but comes back up
immediately as soon as the laptop resumes and it
even "remembered" that I had pressed the ENTER key.
Best,
Gianluca
Ciao Giunluca,
I don't use openSUSE so I don't have an answer about the "Sleep" button.
Simplest way is to just give it a go and see
what happens, you will quickly know whether it will hibernate or suspend to RAM.
Cheers
Michele
