maybe

Did you try chmod-ing it ???

/tmp/.X11-unix is usually there anyway,
         created as part of X or kde etc

It's rare that FreeNX needs to create it
BUT
if your distro now uses somewhere else for local X sessions,
or
it gets removed for some reason
then
you will run into that bug.

nxagent isa modded  XFree86 . . . 
. . . everyone else uses Xorg, which is moving on . . .

It shouldn't be, but that directory should be searchable by everyone . . 
i.e. the x bits should be set

Don't do that

Does lubuntu work locally i.e without NX ( that will be Xorg )

Try chmod-ing
         /tmp/.X11-unix
