Hi, meanwhile I solved the problem with the overlayed keypad. I had to configure: /etc/X11/xkb/types/extra /etc/X11/xkb/types/basic To use the config I had to configure my display manager to call the Xserver with the +kb option. Now I can switch between the keypad and the basic keys on the keyboard. Pressing keys now produces the expected results. Cheers, Steffen Schuler
