You should be able to bind the screensaver lock command to CTRL+ALT+L by editing your Lubuntu keyboard & mouse configuration file

Add the following to ~/.config/openbox/lubuntu-rc.xml

<keybind key="C-A-L">      
  <action name="Execute">        
    <command>xscreensaver-command -lock</command>      
  </action>    
</keybind>

This should be located inbetween the XML tags

<keyboard>
...
</keyboard

enter image description here

Logout and login for the changes to take effect.

Type openbox --reconfigure in terminal for changes to take effect. This is GNU/Linux we're talking about—logout/login is superfluous. –  Richard Feb 27 '12 at 18:17
  1. I'm not good at scripts but I would do it like this (and it should work):
    lock.sh contents:

    xscreensaver-command -lock

    in terminal:
    sh ./lock.sh

  2. Better way is to create a .desktop file (which you can place on panel inside of "Application launch bar" applet, and it will be in main menu all the time). In /usr/share/applications create file lock.desktop and it should contain:

    [Desktop Entry]
    Type=Application
    Icon={path to icon you like}
    Name={what would you like to name it}
    Categories=Utility; {this will place it in Accessories menu in your main menu}
    Exec=xscreensaver-command -lock
    NoDisplay=false {if you set this to true you will not see it in menu and while adding to panel}

Save it and it should appear in menu (maybe after few seconds)

you're welcome. If you run into any troubles with this, write here, will help as much as I can –  foxy Nov 17 '11 at 15:59
    
About the keybinding (sorry, can't commit on others' answers): you should just copy the text which fossfreedom posted in that place, it's not there yet. –  foxy Nov 17 '11 at 19:03

I would elaborate/combine some of the answers. First (in a terminal) start your editor:

vi ~/.config/openbox/lubuntu-rc.xml

Then search for the mentioned faulty code:

<keybind key="C-A-L">      
  <action name="Execute">        
    <command>xscreensaver-command -lock</command>      
  </action>    
</keybind>

and change it to use the dm-tool:

<keybind key="C-A-L">      
  <action name="Execute">        
    <command>dm-tool lock</command>      
  </action>    
</keybind>

Then add a section, so the Windows+L combination works too:

<keybind key="W-L">
  <action name="Execute">        
    <command>dm-tool lock</command>      
  </action>    
</keybind>

Finally, finish the editor (saving the file) and activate it:

openbox --reconfigure

Good luck and thanks for all the answers found here...
