Odd; this should work.  What happens when you try this?

The different DISPLAY settings that you describe shouldn't be a problem.
The .Xauthority file can contain a list of several authentication keys,
each associated with a different display.  If the current display is
already in the file, the associated authentication key will be overwritten;
otherwise, it will be added.

Use `xauth list' to see a list of what's going on here.
