Note: Archlinux and Xorg Keyboard Layout

Archlinux for me seems to miss any magic that takes care of automatically providing the correct keymap to xorg's input driver. To make udev provide the correct settings to xorg, this small udev-rule works.

[root@fbsd ~]# cat /etc/udev/rules.d/99_keyboard_keymap.rules
SUBSYSTEM=="input", ENV{ID_INPUT_KEYBOARD}=="1", ENV{XKBMODEL}="pc105", ENV{XKBLAYOUT}="de", ENV{XKBVARIANT}="nodeadkeys"

So far it's understood by xorg just fine.
