If this is a new install, also sure to add hald_enable="YES" to
/etc/rc.conf as x uses hal to detect your hardware.
Something that might be useful here to see whats going on is to launch X
X -verbose -probeonly
This will show you what hardware/drivers and screen modes it's
detecting. It'll also show you problems if it has any.
Also, you want to make sure you have a compatible video driver is
installed. 'vesa' usually works, but barely. Check out
/usr/ports/x11-drivers/xf86-video-* - if you know what your hardware is,
it should be simple to figure out what driver you need.
Not sure how helpful this would be as it seems like PC-BSD should
already have hal enabled and the more common drivers already available.
At least this is a place to start.
