Comment 15 for bug 1441460

I confirm this issue. I am running xubuntu 17.10. i.e. xfce with lightdm on my thinkpad x230. None of the mentioned work-arounds works for me as I don't want to give up locking the screen with a password. The policy suggestions seem to have no affect (in addition to allowing me to select suspend in xfce). I can suspend manually and also suspend when closing the lid. But leaving my laptop sitting without power with a locked screen will not suspend and drain the battery.

So, the agreed work-around is NOT to use lightdm if you want power management and a password secured login? Would upgrading to bionic beaver (18.04) make any difference?
