Using --use-display produces the following error message:

Since xpra v2.3-r19246 xpra does not use/regard XAUTHORITY to access a display with --use-display if the specified display uses cookie authentication. It fails with 'no protocol specified'.

Code to reproduce:

/usr/bin/Xvfb :40 -screen 0 1920x1080x24 \
  -nolisten tcp -dpms -s off -retro \
  +extension Composite +extension RANDR +extension RENDER +extension GLX\
  +extension XTEST \
  -auth /tmp/cookie \
  &

sleep 2
xauth -f /tmp/cookie add :40 . $(mcookie)
# env DISPLAY=:40 XAUTHORITY=/tmp/cookie xterm   #no error message
env DISPLAY=:40 XAUTHORITY=/tmp/cookie xpra start :40 --use-display  --start-via-proxy=no --daemon=no

It used to be the case that you could specify --with-Xdummy --with-Xdummy_wrapper when running setup.py build to force selection of the Xdummy wrapper rather than Xvfb without having the Xorg detection stuff kick in. Subsequently, running a python setup.py --skip-build install (without --with-Xdummy --with-Xdummy_wrapper) would install an xpra.conf file which used Xdummy, as expected.

Currently, unless --with-Xdummy --with-Xdummy_wrapper is specified both with build and install, the Xorg detection stuff kicks in during install, and a xpra.conf using Xvfb is installed.

Logically, I expect xpra.conf to be created during build, and whatever is present during install is just installed if we're using --skip-build. I'm not sure when this crept in.
