[Bug 1574120] Re: Notebook doesn't suspend when lid is closed after update to 16.04

[Bob]

@unusedusername I found a snippet somewhere that helped me do things
when my lid is closed (or rather when the session is locked). Since your
laptop switches to airplane mode something is detecting it so maybe this
helps. Put this in a script and run it, then close lid and open lid. Do
you get any output?

<snip>
#!/bin/sh
iface=org.freedesktop.login1.Session
dbus-monitor --system --profile "type=signal,interface=$iface" 2>/dev/null |
 while read type stamp sender dest path intf member; do
  case "$member" in
    *Lock)
        date
        echo LOCKED at $stamp ;;
    *Unlock)
        date
        echo UNLOCKED at $stamp ;;
    *)
  esac
done

</snip>

If it works you could even insert a suspend command and run this in the
background to avoid having to use the mouse.

Bug description:
  My notebook does not suspend after upgrading from 15.10 to 16.04.

  According to system settings the notebook should suspend when lid is
  closed but actually this does not happen. Instead it continues to run
  as if nothing had happened.

  With the previous versions of ubuntu (14.04-15.10) everything worked
  fine.

  My System: HP Pavilion dv7.
