Comment 12 for bug 1431149

I have the same problem on a fresh install of Xubuntu 15.10.

* Suspending without closing laptop lid is fine.
* Turning off lock screen on sleep makes no difference (screen is black when opened even without a lock screen).
* Removing light-locker makes no difference.
* Installing xscreensaver makes no difference.
* Problem persists whether I choose lock screen, turn off display or suspend on action for closing laptop lid.
* xrandr --auto (and switching consoles) works.
