actkbd and screen rotation in archlinux

actkbd is in AUR. I need it so the tablet keys on X220 tablet can serve more use (e.g., differentiate between long and short press, etc.)

In order for the rotation script triggered by actkbd to be able to communicate with X, we need to start actkbd with the DISPLAY=:0 environment variable. The AUR package created the /etc/rc.d/actkbd entry. Just change

[ ! -f $PIDFILE ] && /usr/sbin/actkbd -D -q -p $PIDFILE

to

[ ! -f $PIDFILE ] && DISPLAY=:0 /usr/sbin/actkbd -D -q -p $PIDFILE
