For keyboard/ mouse to work after an Arch Linux install, you need to do this :
pacman -S hal dbus
then go in to /etc/rc.conf and put hal in the DEAMONS line like this :
DAEMONS=(syslog-ng hal network netfs ...)
Most of the stuff below is stuff for me, so i can come back and reference stuff when "I" need to. I do not guarantee that using any resource on this page will work for you, as it is all tailors for my own system.
