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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1205384 Title: Lock can be circumvented by switching to console To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1205384/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
