Until such a possible fix is distributed for Lite users (if ever):
I found that this suggestion at the end of the bug report in second link above
also removes the bug of "freezing" I mentioned above. I detailed the solution at Zorin OS 17.2 Lite Freezes after kept idle (laptop lid closed) - #32 by vic
@StarTreker , that can be used for just disabling the lid switch (in Lite/ Xfce); have you tried it?
thanks, I'll try it if the new solution fails.
