[winswitch] [newb] 0.1.0 fedora nothing happens

[Neal Becker]

Built on fedora f16 x86_64.  Install like this:

python setup.py install --user

Then:

xpra start :100

DISPLAY=:100 xterm

[sits and waits but nothing happens...]

---nbecker1-100.log:

Xlib:  extension "RANDR" missing on display ":100".
Xlib:  extension "RANDR" missing on display ":100".

xpra is ready.

All commands run as user (not root).

Any ideas?
