your issue is with xfce. xset is talking to the xserver configuring its
timeout. then something in xfce knows what xfce thinks thew setting should be
in xfce config files and modifies this after you - last guy in wins. this has
nothing to do with linux nor even the xserver. it's tod with your desktop
environment of choice. use another that allows settings to disable this (or
find out how to do this in xfce if it can do it). you keep looking elsewhere
for a solution and blaming other things.
