In any terminal operating under GNOME, if I press Ctrl+C, I only see a question mark. Same goes for Ctrl+Z. The output of
stty -a | grep intr is:
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = M-^?; eol2 = M-^?;
I can use the sequence under all other tty's (outside X), and can also use it for another user; only one user is affected. How can I fix this?
