In future, I suspect you'll need to take questions like this that don't
really have anything to do with Python to a Raspberry Pi forum or e-mail
list.  Or a general Linux list.

Short answer:

Edit /etc/sudoers and add this line somewhere in it (probably near other
lines that look similar):

Defaults env_keep += "DISPLAY XAUTHORITY"

If that doesn't work, then you'll have to talk to folks running the
Rasbian on their Pi.  Sometimes XAUTHORITY isn't set.
