Thanks for the tip. I made those changes to xorg.conf and I still have
the "stacked" double image (nice description for it, BTW). So, I'm now
looking at /etc/ati/amdpcsb file, but I have NO idea how to correlate
those values to xorg.conf. What should I be looking for? Should I post
that file?
Thanks,
Harry
