Dell xps 15 9550 waking up from sleep freez

I own a xps 15 9550 and after the latest updates sleep does not seem to work anymore, it seems to go to sleep but the freeze happens when I try to wake it up.

So it’s X related, looks like it works when in wayland it can wake up just fine.

I just looked up about the wayland. How can I migrate into wayland from X.org?
It seems that I need to learn a lot about wayland even for a 10-year suse user.

Many thanks in advance for any advice.
