Plasma 5 and hybrid sleep

Hello, I have Slackware-current 64-bit with Plasma 5 (5.19.1)
installed.

I cannot use Suspend to RAM as it kills touchpad.
However Hybrid Sleep (run from console) works well.
I was trying to enable Hybrid Sleep in Plasma 5, however it does not work:
Closing lid just logs user out
Selecting from KDE Menu is not possible (missing option)
also
selecting Hybernate from KDE menu only logs user out.

system is capable to hibernate and hybrid hibernate:
pm-hibernate
pm-suspend-hybrid
from console work
lilo.conf has
append="resume=/dev/sda2"

thank you
