I got hit with this bug on chimaera when trying to connect via x11vnc. The
auth failed.

ps ax |grep auth gives me

 6147 tty7     Ssl+   0:00 /usr/lib/xorg/Xorg :0 -seat seat0 -auth
/var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
 6270 tty8     Ssl+   0:02 /usr/lib/xorg/Xorg :1 -seat seat0 -auth
/var/run/lightdm/root/:1 -nolisten tcp vt8 -novtswitch

After setting 'xserver-share=true' in
/usr/share/lightdm/lightdm.conf.d/01_debian.conf
fixes the problem. Only one display shows up with ps and I can connect
with vnc.
