Working Power Manager in Lubuntu 14.04?

Hiya. First mail to a mailing list ever so I apoligize for anything I
shouldn't have done. Thought that maybe this should be a question on
askubuntu, but this way it's problably better.

I'm running Lubuntu 14.04, and loving the blazing speed. It's the
fastest OS I ever had. I can run a 64 bit system on 738MB RAM.

The only thing I don't like is the power manager. I can't get it to
work. I set 'Laptop Mode' on in 'Default applications for LXSession',
xfce4-power-manager starts up correctly, handles everything correctly,
except putting the computer to sleep.

I heard that xfce4-power-manager isn't patched to work with systemd. I
found a solution on Ask Ubuntu that will enable xfce4-power-manager to
put the laptop to sleep when the lid shuts down, by setting
"HandleLidSwitch" in /etc/systemd/logind.conf to "ignore". I tried, and
indeed, xfce4-power-manager was able to put the laptop to sleep on lid
close, but it was buggy (it didn't sleep every time), and it didn't
lock the screen.

So I tried the opposite, as suggested in the answer. I set
"HandleLidSwitch" to the default (suspend), and turned off all lid
actions in xfce4-power-manager. A little improvment, but still, doesn't
work all the time, sometimes fails or just ignores, but at least it
locks the screen.

Has anyone here got a working power manager? If yes, how?
