Lock Screen Not Working

I recently installed BunsenLabs on my PC. In  the past when I've installed it I've been able to lock my screen but on this recent install I'm unable to to. When I right-click and select Lock Screen nothing happens at all. Anyone else getting this issue?

Re: Lock Screen Not Working

The Lock Screen menu item runs `bl-lock`, which is a wrapper script for light-locker. Others have reported issues in the past with light-locker, so you may want to search for those threads.

What is the output if you run the script in a terminal?

bl-lock

Re: Lock Screen Not Working

@usuallymatt:  You could also try using xscreensaver.  Edit the bl-lock file as superuser, /usr/bin/bl-lock, and substitute xscreensaver-command -lock for all instances of light-locker-command -l.  The final results should look something like this:

#!/bin/bash
# bl-lock
# -------
# This is a wrapper for the 'xscreensaver-command -lock' command.
# If running in live mode, offer up a prompt detailing the live session password.
# Else, run xscreensaver-command -lock.

LOCK_COMMAND=(xscreensaver-command -lock)

which ${LOCK_COMMAND[0]} >/dev/null 2>&1 || {
    echo "$0: ${LOCK_COMMAND[0]} no such command." >&2
    exit 1
}

if [ -d /lib/live ] && [ ! -f /home/$USER/.config/bunsen/bl-lock ]; then
    yad --image='bunsenlabs' --window-icon='distributor-logo-bunsenlabs' --center --borders=20 --button=gtk-ok --fixed --on-top --title='Lock screen info:' --text='Lock screen has detected you are running a live session.\nThe username needed to unlock the screen is "user" and the password is "live".\nThis notice will only be displayed once per live session.'
    mkdir -p /home/$USER/.config/bunsen
    touch /home/$USER/.config/bunsen/bl-lock
fi

"${LOCK_COMMAND[@]}"

exit 0

However, note that every update of bunsen-utilities will overwrite what you've done.  To remedy that, checkout johnraff's suggestion.  I haven't tried his suggestion yet, so I can't vouch for whether it will work or not.

Re: Lock Screen Not Working

Aha. Looks like light-locker wasn't running. I've since added it to my autostart and everything works just fine.
With regards to xscreensaver I've never been able to load the Screen Saver screen even on Crunchbang. When I load the screensaver menu item it says "Failed to execute child process "xscreensaver-demo" (no such file or directory). It doesn't matter too much to me because I just use the power management menu to set a blank out time.

That shouldn't be necessary in fact. Do you have a file 'light-locker.desktop' in /etc/xdg/autostart? How about in $HOME/.config/autostart? The second may not exist, but if it does, it might be preventing light-locker from starting.
