This is a key bit: Jan 17 07:54:33 workstation gnome-session[2959]: WARNING: Application 'gnome-shell.desktop' killed by signal 11
The lock screen is integrated into the compositor (gnome-shell) in 3.6. An unfortunate side effect of this is that if the compositor crashes, it will get auto-restarted, and we "fail open". In prior versions of GNOME, "gnome-screensaver" was an indepenent process. Clearly it would make sense to attempt to preserve the "screen is locked" state, but that'd still allow a window in which the session was accessible. The real fix here is to figure out why gnome-shell is crashing and ensure it doesn't. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gdm in Ubuntu. https://bugs.launchpad.net/bugs/1064584 Title: Locked gnome session unlocks without password authentication Status in “gdm” package in Ubuntu: Confirmed Bug description: When switching between users in ubuntu 12.10 using gdm a rather unpleasant behaviour can occur when a locked session unlocks without password authentication. Steps to reproduce: 1. Login as user1 (password required) 2. Lock screen 3. Select login as other user 4. Login in user2 which does not require any password, e.g. guest 5. Logout user2 6. Screen returns to unlocked session for user1 It doesn't happen every time but rather frequently so I suspect some sort of race involved.
