linux set up mouse via terminal

SET mouse to LiftHand: 

xmodmap -e "pointer = 3 2 1"
in a terminal should work. If you want to run that command at the start of lightdm (the default login screen), you can edit /etc/lightdm/lightdm.conf like described here - use the xmodmap command instead of xbacklight in the script, of course.
