I'm quite sure I found the reason for this behavior - A closer look at my settings showed following:
[Screen:] Turn off after: 10 minutes Lock Screen after: Screen turns off [Power] Suspend when inactive for: 10 minutes Therefore, what most probably happens is: Both Suspend and Screen Lock are in this setting initiated at the same instant, however the Suspend mode preempts the Screen Lock and so after the systems is resumed, the Screen Lock is subsequently initiated. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/889278 Title: Screen is locked again after unsuspend and successful authentication Status in OEM Priority Project: New Status in OEM Priority Project oneiric series: New Status in OEM Priority Project precise series: New Status in “gnome-settings-daemon” package in Ubuntu: Confirmed Bug description: After unsuspending and successful authentication, the screen is locked again a few seconds later without any possibility to prevent this. This occurs only if the machine is suspended automatically after a certain inactive time, however not if it is initiated by the user.
