Fedora: After Exiting Su Root, Backspace Prints ^?
Had the weirdest problem on Fedora 20. Any time I was in the terminal, if I used su to set user to root, once I exited back into my normal shell, any backspace would produce the ^? character.
$ ./commaf^?^?^?^C
$ ./command --opy^?^C
$ god damn it
This problem is solved thusly:
  1. Open your terminal.
  2. Edit → Profile Preferences → Compatibility
  3. Select Backspace key generates, and change it from ASCII DEL to Automatic
And you're done!
