Hi Juraj,
I have had no trouble with the xfce4-power-manager putting my computer
to sleep.
The graphics card is usually the main issue with Suspend.  What kind of
card do you have?
you can use something like
lspci | grep VGA
to get the exact model.
This might help us figure out how to help you better :)
