I can confirm this bug on lubuntu 13.10 amd64. The workaround I chose (following #22) was to:
1) Install suckless-tools: sudo apt-get install suckless-tools 2) edit /usr/bin/lxlock (sudo nano /usr/bin/lxlock). It tries to trigger screen locking using various tools, one of them is in fact slock, the tool provided by suckless-tools. The whole contents can be erased and just write "slock" instead. What I did was to add the "el" prefix to the first "if", and move the "elif" testing and triggering slock to the top (removing the "el" prefix). -- 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
