Comment 24 for bug 1307545

I should add a few things concerning my comments #22 and #23: All outputs are from a utopic system. For light-locker to work properly in utopic (see https://bugs.launchpad.net/ubuntu/+source/xubuntu-default-settings/+bug/1303736?comments=all) the xfpm xconf setting "/xfce4-power-manager/logind-handle-lid-switch" has to be set to "true" (this seems to have changed since trusty). This means the findings in #22, #23 are still valid, but with these settings the screen stays blank after unlocking after resume.
If one uses the proper settings for light-locker (/xfce4-power-manager/logind-handle-lid-switch = true) in utopic, then the system suspends in either case (lid close action: lock or blank).
