WoW! Everything I tried worked!
I've been using Ubu Tweak since day-one, but I was about to give-up on a Unity version (for want of a different term). Functionality was sorely missing (compared to older versions) and many things didn't work. Computer Janitor comes to mind. When I clicked on System --> Old Kernel, it would hard lock -- had to killall my way out of it.
BTW, I use this PPA (same church, different pew)...
deb http://ppa.launchpad.net/tualatrix/next/ubuntu quantal main #Ubuntu Tweak-next
deb-src http://ppa.launchpad.net/tualatrix/next/ubuntu quantal main #Ubuntu Tweak-next (Source Code)
