Public bug reported: I don't know whether this is a unity bug or elsewhere, but I'm noticing this problem after upgrading from utopic to vivid.
On your desktop, go to System Settings -> Brightness and Lock and set the "turn screen off" time to 1 hour. Wait 10 minutes without using your desktop, and the screen goes blank. However, even though "Lock screen after" is set to "Screen turns off", the lock screen is not activated. ** Affects: unity (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.
