I'm trying out Linux Mint 11 with LXDE. I'm used to being able to lock the screen with a keyboard combination (for example, Win+L on Windows) rather than tracking down a menu or clicking an icon.
Web search returned Ctrl+Alt+L as a default combination to lock the screen, but this did nothing for me.
Is there a way to do this in LXDE?
Update:
The link to http://wiki.lxde.org in the answer has the required steps, except that in Mint 11 the file is called mintlxde-rc.xml
