To disable Jaunty’s stupid warning dialog when a program started by Terminal is still running:

gconf-editor, apps > gnome-terminal > global > uncheck confirm_window_close

That will also disable the warning if you have multiple tabs, but I don’t give a damn–that warning is very Windows-y and annoying as hell. I already know that closing a terminal will kill the app (most of ’em–not Conky), so STFU.

To re-enable Ctrl-Alt-Bksp, which is disabled by default in Jaunty because people are stupid (how the fuck does anyone short of a mouth-breathing idiot “accidentally” hit a well-known three-key combination??) Install dontzap, then:

dontzap –disable

Okay, so I read the reasoning behind disabling (actually changing) the key combination, and it almost makes sense. It’s because backspace and delete are often side-by-side on laptop keyboards, and many Ubuntu users are coming from Windows, so they might think the three-fingered Windows salute does what it does in Windows (it doesn’t–in Jaunty, it brings up the shutdown dialog, but you can change that), and might accidentally hit Ctrl-Alt-Bksp instead, kicking themselves out of X without saving anything that’s open, and into a scary black screen where they don’t know what to do. I like Ubuntu still, and I know they mean well, but the n00b-friendly stuff is starting to get on my nerves a little. Maybe next time, I’ll try Arch or something.
