Confirmed - Installing 'xscreensaver' alone will NOT fix the issue. Confirmed - the workaround on this post: https://bugs.launchpad.net/ubuntu/+source/lxsession/+bug/1205384/comments/35 Has solved the issue for me.
Indeed, NO need for xscreensaver service to start automatically so I can confirm that it is OKAY to install the package (xscreensaver) by default to solve this AS LONG AS the service is not going to work by default and that is of course, if the Developers will not find the right solution for this issue without installing 'xscreensaver' :) Thanks! -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1205384 Title: Lock can be circumvented by switching to console Status in LXDE - Lightweight X11 Desktop Environment: New Status in “lightdm” package in Ubuntu: Invalid Status in “lxsession” package in Ubuntu: In Progress Bug description: Steps to reproduce: 1)lock your screen using "dm-tool switch-to-greeter" or "dm-tool lock" 2)switch to console via ctrl+alt+F1 3)switch back to X via ctrl+alt+F7 Result: session is unlocked without entering a password Expected behaviour: session should still be locked when switching back to X ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: lightdm 1.7.7-0ubuntu2 ProcVersionSignature: Ubuntu 3.10.0-5.15-generic 3.10.2 Uname: Linux 3.10.0-5-generic i686 ApportVersion: 2.11-0ubuntu1 Architecture: i386 Date: Fri Jul 26 17:30:23 2013 InstallationDate: Installed on 2013-07-26 (0 days ago) InstallationMedia: Lubuntu 13.10 "Saucy Salamander" - Alpha i386 (20130723.1) MarkForUpload: True SourcePackage: lightdm UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/lxde/+bug/1205384/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
