vncserver works when started as user, but not as root.

[James Weatherall]

Kenan,

The difference between the two cases isn't just the user you're running the
desktop as, but also the method you're using to invoke the vncserver command,
and the command-line you're giving it.  I'd therefore suggest:

1.  Testing whether "vncserver :1" works for root, e.g. sudo vncserver :1
2.  Testing whether "vncserver -geometry 800x600 -nolisten tcp -nohttpd
-localhost" works for root in a similar fashion.
3.  Once you have got a command line that works, in (2), put that in the
/etc/sysconfig/vncservers and try starting it via /sbin/service again.

Cheers,
