Keyboard Layout

I have suffered from the problem, that on a Danish MacBook the keyboard settings just doesn't map correct - not even if you choose the correct settings in system preferences.

Here's what you can do to fix it (this approach will work for any keyboard that is out of skew - not just Mac).

Use the command

xmodmap -pke

The this command will list the current settings to stdout. The output is in a format that you can feed back to the xmodmap commands, so all you have to do now is to pipe it into a file, and manipulate it a little bit before you load it back.

To determine which keys correspond to which keysymnames and keycode numbers use the command. While it's running hit a key.

Manipulate the xmodmap file to reflect you rkeyboard layout.

Save the  xmodmap file you generated with an .xmodmap extension in you home directory, Ubuntu will then offer you to load that xmodmap file next time you log in.

This is what my .xmodmap file looks like when I have modified it to support a Danish MacBook keyboard layout:
