Keyboard setup 2. You have two tools for configuring your keyboard. Under plain Linux you have loadkeys and under X11 you have xmodmap . Dead keys are explained in section Dead keys and accented characters .
Details vary between distributions.
Versions of XFree86 up to and including v3.1.2 will normally follow the keymap used by plain Linux, but you can modify keyboard behavior under X11 with xmodmap . Usually the X11 initialization process will run this command automatically if you have a file called .Xmodmap in your home directory. See section Dead keys and accented characters for more information on this. Usually you can do this by uncommenting the appropriate line. In XFree86 v3.1.2 you can use AltGr as an alias for RightAlt .
