*** This bug is a security vulnerability ***
Public security bug reported:
In Quantal in Raring, gnome-screensaver no longer auto starts in the
Unity session because the .desktop file contains the following line:
AutostartCondition=GNOME3 if-session gnome-fallback
This results in screen locking being broken.
Steps to reproduce:
1- Reboot
2- Login to session
3- Wait 10 minutes
Expected results:
- gnome-screensaver process autostarted in session
- screen locks after 10 minutes
Actual results:
- gnome-screensaver process doesn't get autostarted
- screen only blanks after 10 minutes, and doesn't lock.
Manually locking the screen results in the gnome-screensaver process
being spawned, which fixed screen locking for the remainder of the
session.
