Light locker / forced lock screen

The root cause is that the user-specific light-locker.desktop file doesn't override the system-wide one.  So, even if the user configures light-locker to not start at all, it still runs with the default configuration parameters.

Warning: This will disable system-wide default screen locking.  If you want to enable locking for a specific user, you'll need to edit the Exec= line in the ~/.config/autostart/light-locker.desktop file for each user (or use GUI after reboot).  Configuring this through "Preferences >> Light Locker Settings" may do this (once the system-wide file is moved out of the way), but I haven't tried this.

Step 1: Disable system-wide startup of light-locker.  This will allow the per-user .desktop file to be executed instead.

sudo mv /etc/xdg/autostart/light-locker.desktop /etc/xdg/autostart/light-locker.desktop.bak

To re-enable this, you would just rename the file so it no longer has the .bak extension.

Step 2: reboot

Step 3: Edit the user-specific light-locker.desktop file and reboot, or use GUI lightlocker

Open ~/.config/autostart/light-locker.desktop in a text editor.

Edit the line that begins Exec= so it is only Exec=. That is, there is no command specified which means light-locker won't be started.

Mapping Windows key to menu

File: ~/.config/openbox/lubuntu-rc.xml

<keybind key="Super_L">  <action name="Execute">    <command>lxpanelctl menu</command>  </action> </keybind>

This command should work as well but didn’t for me gconftool-2 --set /apps/metacity/global_keybindings/panel_main_menu --type string "Super_L"
