Hi people, I've just successfully installed FreeBSD 6.0 (3rd time lucky

) and am having problems configuring X.org. I followed the instructions in the handbook, both editing xorg.conf by hand and then using xorgcfg but it doesn't seem to like it. When I do a "startx", I see the following lines:
xauth: (argv):1: bad display name "nick.Belkin:0" in "list" command
xauth: (stdin):1: bad display name "nick.Belkin:0" in "add" command.
After this, the server looks like it's starting, but all I see are loads of vertical lines, coloured in different shades of green.
For HorizSync and VertRefresh settings in xorg.conf, I tried to use the same values as I use in Slackware (this is ok, right? It just depends on the hardware so it should be, at least this is my thinking), but this didn't make a difference.
Graphics card: NVIDIA GeForce 6600 256 MB, monitor: Samsung SyncMaster 753s.
Xorg.0.log and
xorg.conf. I hope these links work. If not, does anyone know where I can host them temporarily? I don't have webspace of my own and they're a bit too long to post here.
Also, how do I become root in FreeBSD? When I try "su", it gives "nick su: BAD SU nick to root on /dev/ttyv0" :/. I mean, I can log in as root, but I should be able to use su as well, shouldn't I?
One last thing: I'm amazed with how little needed doing to configure my wireless card!
Any help appreciated, thanks.
