Hey everyone,

I've been struggling to get VNC working with multiple users. Upon
digging into it I realized that it's because the X display number is
fixed in the xvnc service, even when in inetd mode, so only the first
user who connects gets a desktop and everyone else gets an error. By
omitting the display number when using inetd, xvnc just picks an
unused display and I'm now able to log in with multiple user accounts.

The patch is a one-liner and hopefully not very controversial. :)
