I made the upgrade on my Lubuntu machine to 13.10 yesterday. Everything seemed to go smoothly except one niggling thing I can't seem to fix. Previously, I had set the power button to suspend my computer when it was pressed- I was able to set this in the Xfce Power manager.
However after the upgrade, pressing the power button will shutdown the computer rather than suspending. I did a test and checked the logs and found this when I pressed the power button:
auth.log:Oct 21 22:48:35 Inspiron-1564 systemd-logind[748]: Power key pressed.
auth.log:Oct 21 22:48:35 Inspiron-1564 systemd-logind[748]: Powering Off...
auth.log:Oct 21 22:48:35 Inspiron-1564 systemd-logind[748]: System is powering down.
I'm stuck here. Somehow systemd-logind thinks I want to shut the computer down, but I'm not sure where those settings may be. Any help is greatly appreciated.
Additionally, while this post has an answer that has a roundabout method of solving the problem, I will not accept that as an answer because it essentially doesn't work, and is not how the problem should be solved.
