Comment 26 for bug 1307545

> Now, b3nmore, the bottom line of your feedback is that the bug does not affect utopic with default settings.

No (sorry, I should have mentioned, that #20 is from the same system), with the default settings in utopic we have:
lid action: result:
switch off display switches off display
lock screen suspends (and locks screen)

However, with those settings, the screen stays blank after unlocking a system resumed from a lid closed triggered suspend. To correct this issue, "xfce4-power-manager/logind-handle-lid-switch" has to be set to "true". Btw., this is what happens, if one disables and enables light-locker via the gui [1], [2].

Now, with the correct light-locker settings we get:
lid action: result:
switch off display suspends (and locks screen)
lock screen suspends (and locks screen)
