For those people who find that pressing one of the special keys causes the mouse to jump to (0,0), could you please attach the log generated by input-events when that occurs? You'd want to run “sudo input-events $N” (replacing $N with the input device number) in a terminal, then press a special key to trigger the behaviour, then copy the output here.

You can work out what your input device number is from your /var/log/Xorg.0.log. For example, this person has their special keys on input device 3 (/dev/input/event3):

Your special-key device will be the one with all those incorrect properties - 1 mouse button, scroll wheels, relative & absolute axes.
