Comment 89 for bug 255008

None of these fixes worked for me on Intrepid beta. I tried both Dell wired USB and Kensington MAC KBD.

Here are relevant inputs: setxkbmap -print
xkb_keymap {
        xkb_keycodes { include "evdev+aliases(qwerty)" };
        xkb_types { include "complete" };
        xkb_compat { include "complete" };
        xkb_symbols { include "pc+us(mac)+inet(evdev)" };
        xkb_geometry { include "pc(pc104)" };
};

and xorg.conf

Section "InputDevice"
    # generated from default
    Identifier "Keyboard0"
    Driver "kbd"
EndSection

The problem started after an update today, is also described here http://kubuntuforums.net/forums/index.php?topic=3097316.0

Thanks for your kind feedback.
