The report in /var/log/Xorg.0.log:

"_XSERVTransMakeAllCOTSServerListeners: server already running"

suggests the system (user: gdm, uid: 116) display manager X server on VT7 owns/uses the socket in "/tmp/.X11-unix/" which prevents the user (uid:1000) display manager on VT2 from using the same socket.
