Are you hoping to run parti, or xpra?

Currently you are running parti, but I don't know why you would want
to run parti against Xvfb. (parti is a traditional window manager --
or the stub of what may someday become one -- and Xvfb is an X server
that does not display on the screen at all, so you can't interact with
it.)

The ./try-parti script will automatically start parti against Xephyr,
which is a X server that displays inside a window in your existing X
session.

That's... weird. The code itself appears correct.

What version of Python and Pyrex are you using?

Yes, parti and xpra require compositing support. The distributed
scripts should all take care of that automatically -- let me know if
you run into any problems with them -- but if you're setting up X
servers by hand you might need to do some tweaking of course.
