Comment 0 for bug 1413894

I pressed a hotkey to run "xfce4-session-logout -s", closed the laptop lid, pulled the earphone and the USB mouse out. I came back later and the machine wasn't sleeping but was displaying a black screen (with background-light). No response for any keys, and key-combinations. CapsLock LED on. There is a Wireless ON-OFF button that changed from white to orange when once pressed.
I couldn't connect with ssh.
I powered the laptop off long-pressing the power button.
