Well, #19 describes a workaround, but it requires using a package from a PPA repository https://launchpad.net/~light-locker/+archive/release .
Another workaround that uses a package from Universe repository of Ubuntu and works around Bug #1229486, too, is here: Install suckless- tools, edit /usr/bin/lxlock to run slock insead of any other locking utility (or add a script named lxlock at /usr/local/bin/ to run slock). Note that slock does not even display password prompt, but a blank screen you have to type password in, and there is no way to swit. xlock would be better, but xlockmore package containing it is no more available in Ubuntu repositories. Neither of those work with xfce4 -power-manager that uses xscreensaver, which have to be run as a daemon; if you are going to suspend/hibernate+lock by xfce4-power-manager, you have to autostart xfce4-power-manager (edit in lxsession-edit) and xscreensaver (how?) and then you may want to use "xscreensaver-command -lock" in lxlock, instead of slock. xscreensaver allows new login. -- 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 “lightdm” package in Ubuntu: Invalid Status in “lxsession” package in Ubuntu: Confirmed 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/ubuntu/+source/lightdm/+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
