It looks like xrandr requires connecting to an X server. When run 
from rc.local, it does not have one. This is one of the things that 
can cause scripts that work fine when you are logged in to fail when 
run in startup scripts or cron jobs. Another thing to watch out for 
is that the environment is not the same when running from the init 
scripts or a cron job.

When you run the script from an xterm, DISPLAY is set, and you have 
the proper authorization to connect to the X server.
