Public bug reported:

This may be a regression of this bug:

https://bugs.launchpad.net/ubuntu/+source/xubuntu-default-
settings/+bug/1303736

I upgraded from 14.04 (where this also did not work) to 14.10.  This is
on a Thinkpad x220.

When I close the lid, the laptop suspends, and when I wake it, light-
locker is running.  After unlocking, the screen power is off.  Running
"xrandr --auto" corrects the issue.

I normally have "HandleLidSwitch=ignore" set in
/etc/systemd/logind.conf, because otherwise, the xfce4-power-manager
setting to only suspend on lid-close when on battery power is ignored.

For debugging purposes, I tried changing the  /xfce4-power-manager
/logind-handle-lid-switch xfconf setting as well as the
HandleLidSwitch=ignore setting in logind.conf.  These are the results:

logind.conf: HandleLidSwitch=ignore
xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-lid-switch -s false
  lid-close: light-locker runs, screen power off after unlock
  lock-screen-command: light-locker runs, screen power on after unlock

xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-lid-switch -s true
  lid-close: light-locker does not run
  lock-screen-command: light-locker runs, screen power on after unlock

default logind.conf:
xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-lid-switch -s false
  lid-close: suspend, light-locker runs, screen power off after unlock
  lock-screen-command: light-locker runs, screen power on after unlock

xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-lid-switch -s true
  lid-close: suspend, light-locker does not run
  lock-screen-command: light-locker runs, screen power on after unlock
