I just installed Lubuntu 11.10. I spend quite a bit of time in Emacs, and I have a bunch of key bindings that rely on the Super key. However, Lubuntu captures the Super key press and opens the main menu every time. This is quite frustrating.

How I do I unbind this super key behavior? I've tried tweaking lubuntu-rc.xml with no luck.

  • OK. BE CAREFUL. The relevant code is buried in the middle of a long, unbroken line and is very hard to see, but it IS there in your ~/.config/openbox/lubuntu-rc.xml. – user40562 Jan 4 '12 at 21:43

Editing .config/openbox/lubuntu-rc.xml (Lubuntu 12.04) worked here. It's line 177, and the original relevant part looked like this: <keybind key="Super_L". Changed it to <keybind key="", logged out/in, and the Super key does nothing.

  • Worked perfectly, thank you. Don't know how I missed that. – Chris Oct 28 '11 at 22:45
  • In the lubuntu-rc.xml that comes with Lubuntu 13.04, there's no entry with the string "Super". – user25656 May 31 '13 at 17:25
  • @vasa1 thanks for commenting. Unfortunately, I've only tested Lubuntu 12.04, and have no first hand experience with 13.04 at all. – mikewhatever Jun 2 '13 at 19:30
  • But Openbox still recognizes the use of Super_L in Lubuntu 13.04. Someone decided to use just Super_L to open the terminal (although the OS and Openbox version weren't specified). I verified that that works in Lubuntu 13.04. – user25656 Jun 3 '13 at 10:11

For more recent LXQt versions, delete the Super_L entry in the shortcut configs, or delete:

Comment=Show/hide main menu

in ~/.config/lxqt/globalkeyshortcuts.conf.

Works for me in Lubuntu 20.04.

You can use Compiz Config Settings Manager to edit the Ubuntu Unity Plugin. On the Behaviour tab, there's a keybinding for "key to show the launcher".
