This is the problem right here.

Local connections to X servers occur through UNIX sockets, in the
directory /tmp/.X11-unix; for example, a DISPLAY of :100 corresponds to
/tmp/.X11-unix/X100.  The X server will not create that directory unless
run as root, because the directory must be owned by root to prevent
security problems.  On Debian systems, the X packages solve this problem
by setting up /tmp/.X11-unix (and /tmp/.ICE-unix, used for the X
Inter-Client Exchange protocol) in an init.d script.  You could also
just run the server once as root to set up the directories.  This is
generally only a problem with X servers that don't touch display
hardware, as servers that do generally must run as root anyway.
