Well, I found nothing useful. Interesting is, that when I tried live USB with Kubuntu 18.10, the screen is on after resume, but mouse and keyboard does not work.
When I tried live USB with Kubuntu 19.04, the screen, keyboard and mouse is off, I just see the non-moving cursor on black background.
Interesting that sleep and wake works fine in Manjaro live USB with kernel 4.19. So it should work in Ubuntu too.
Okay, it seems that the freezing in Kubuntu was caused my by USB wifi dongle used for Mac OS 🙂 I found it after my Kubuntu did not freeze after suspend when I had my Manjaro USB inserted instead of wifi dongle 🙂
problem solved (partially)
Interesting, with diffetent wifi dongle the problem does not exist at all.
