Comment 8 for bug 938302

> An alternative might be to consider the unlock screen as the exception instead of the display manager.
That's safer, yes. We can probably check if the parent process is gnome-screensaver. If this fails in the future, the worst that can happen is that this bug reappears. I try this.

> About the RUNNING_UNDER_GDM: Does this not mean that Onboard will depend on specific display managers to even start up?
RUNNING_FROM_GDM would suggest that, but last time I checked it's usage wasn't restricted to GDM.
