So my brother went to increase the resolution on his Vostro A90 netbook. Now he can't turn it back since the 'OK' button is off the screen. The window is too tall to be able to use ALT, since the titlebar won't scroll past the screen.
I'm sure there's something to edit manually in the Xorg.conf, but as I don't have his netbook in front of me, and run Jaunty (he runs Hardy) I'm not sure what part to change.
