Although I'm quite happy with Ubuntu 9.04, I find a couple of new features quite annoying. The warning message it pops up whenever you try to close a console with a running program in it falls in this category. Fortunately it's not difficult to disable:
- Open up gconf-editor
- goto /apps/gnome-terminal/global/
- Untick confirm_window_close
All set. As a bonus side effect now closing a terminal with multiple tabs won't pop up a message either.
