How to get X going?

[fheitka%attglobal.net@localhost]

I've installed the X programs and X server on my NetBSD
system.  I can't see how to get the X server going.  Do I 
need a file like XF86Config on Linux?  When I try to start
X I get the message: grfcv3d: Monitor definition not ok.
Looking through the man pages I see nothing about a 
"monitor definition".   I tried making an /etc/grfmodes file
but that didn't seem to help.  A look through the docs at
www.netbsd.org didn't turn up anything either.  Can someone
point me to the missing information?

Thanks!
