Please include the full command lines.
It isn't clear at all how you launched this application within an xpra

You want Xdummy to have RandR:
But Ubuntu breaks their Xorg packages - if you really want RandR, don't
use Ubuntu.

That's a dbus failure. Maybe launch xpra like so:
dbus-launch xpra start ....
0.17 will make this automatic.

Note: if you run from an existing desktop session, or via sudo/su, etc,
you may encounter problems. Best way is to launch as a separate user,
one that does not have any other concurrent desktop environment session.
