Huh, I lie, not wayland related it seems...

If I change the driver to not redirect stderr to dev null:

_XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeAllCOTSServerListeners: server already running
The XKEYBOARD keymap compiler (xkbcomp) reports:
> Internal error:   Could not resolve keysym XF86FullScreen
Errors from xkbcomp are not fatal to the X server
(EE) 
Fatal server error:
(EE) Cannot write display number to fd 4
(EE)

Hah, python2 vs. python3 related, I can start it without issue within a virtualenv with python2...
