Set up the permissions correctly. see man sane-usb. To find out which
file's permissions you need to change, run sane-find-scanner. The easy
way: chmod a+rw /deb/usb/scanner0 (or whatever device). Only good for
systems with only one user.

Not needed if permissions are set up correctly and not a SANE issue,
but...

"cp /home/username/.Xauthority ~/" is one way to avoid that message.

export DISPLAY=:0.0.
