I don't want left alt to do anything, I still want combos like alt-tab to work, but pressing alt shouldn't do anything. By default it focuses the menu, and sometimes makes my cursor flicker.

I disabled it in Windows using AutoHotKey, like this:

; disable a single press of alt, so it's not so annoying

It might be slightly different depending on which version of Ubuntu you are using, but generally you should be able to go to "System Settings -> Keyboard -> Shortcuts", and re-assign the keyboard shortcut which is using "Alt L".

In Ubuntu 14.04, "Alt L" is tied to "Key to show the HUD" under "Launchers" by default.

"Alt L" is the Left Alt key and not the same as Alt+L by the way.
