Screen Immediately Relocks Itself After Unlocking

[Cerin]

Binary package hint: xorg

Steps to reproduce:
1. Manually lock screen.
2. Wait the amount of time for the screensaver to automatically lock screen when idle. (you might want to set this to 1 minute in System->Preferences->Screensaver to speed up testing).
3. Unlock screen by entering password.
4. Try to use system.
5. Notice screen immediately re-locks itself.

What happens:
Screen immediately relocks itself after unlocking.

What should happen:
After unlocking the screen, it should stay unlocked until either manually locked or auto-locked by screensaver.

System:
I'm running Ubuntu 10.04 on a Macbook Pro 5.5.

Other:
I'm not sure if this is the fault of Xorg or not. It's just the closest component I could think of.

as a workaround you need to go to
System -> Preference -> Screensaver
and disable
- Activate screensaver when computer idle
- Lock screen when screensaver is active

After this you do not encounter this issue anymore.
Bear in mind that you need to lock your workstation when you go to grab some donuts in the kitchen :-)

It's almost like there's a second routine running that's locking the screen, and this is being applied over top of the value set in Screensaver Preferences.

I just noticed my screensaver also seems to activate a bit too early. I have the basic "Blank screen" set to activate and lock the screen after 1 hour of inactivity. However, my screen blanks after about 5 minutes of inactivity and doesn't lock. I would expect the screen should not blank until the time specified in the Screensaver Preferences dialog.
