Bug Description

What I want to do:
- Supend machine (suspend-to-ram, standby)
- Wakeup

What I expect to happen:
- upon wakeup I expect the screen to be locked
- no windows should be visible
- entering the passphrase unlocks the screen

What actually happens:
- when I suspend the machine with the expo (Super+S) or scale (Super+W) plugin active
- upon wakeup the screen is unlocked (i.e. desktop fully visible and operable)
- sometimes the screen then eventually locks upon mouse interaction, sometimes it stays unlocked

Ubuntu 12.04.2 up-to-date as of (april 16th 2013)
Compiz 0.9.7.12

Thanks for reporting this bug to Ubuntu.

Sadly, it is not safe to rely upon automatic screen locking mechanisms with X11; the safe thing to do is manually lock the screen before suspending.
