Hi folks,
I screwed up my Pardus 2011 and I need some help in unscrewing it

. I wanted to type a special character and I realized my keyboard wasn't set for handling international characters (for example, an "e" with two dots on top). So I changed to keyboard layout to PC 105 Intl. After I rebooted I can no longer type anything. In fact, I can't even log on because the keyboard is completely dead -- even the num-lock, caps-lock etc. keys don't work anymore. (Obviously the keyboard itself is OK, as I am typing this using the same keyboard.)
Which files do I have to change in order to undo the damage? I am still able to access the install partition.
Second, what do I have to do to be able to type an international character?
Thanks.
