I want that my right alt AltGr behaves as my left control Control_L in linux virtual console.

I use the showkey utility and found out that pressing AltGr generates keycode 100 . So I wrote a rebind.map file with this line:

keycode 100 = Control

And then I've loaded this configuration with loadkeys $(readlink -f rebind.map)

So If I press AltGr + c it should produce the same result as Control + c . And it does, on the first press. On the second press, the keyboard becomes unusable.
