How to solve the problems of the X server, CUPS, and OpenOffice.org on FreeBSD 8.1 amd64

I have reluctantly canceled the RAID array on
Inspiron 531s recently because I unfortunately
had no option but to realize the latest updates
for Fedora 13, such as the alternation of Dracut,
mapping, and mdraid instead of dmraid, didn't
recognize NVIDIA RAID array. It however seemed
I had also better upgrade from FreeBSD 7.1 or the
older version, which had been already installed on
the RAID drive, to the latest FreeBSD 8.1 on the
non-RAID drive at the same time if I was going to
do it. That is why I came to grips with the installation
of FreeBSD 8.1 several times.

First the X server failed to start after installing
FreeBSD 8.1 on the machine with NVIDIA video
card. Therefore I previously downloaded NVIDIA-
FreeBSD-x86_64-256.44.tar.gz in a FAT32 partition
and installed the driver in the CUI editor. The
command lines are given below.

# tar xzf NVIDIA-FreeBSD-x86_64-256.44.tar.gz
# cd NVIDIA-FreeBSD-x86_64-256.44
# make install clean
# nvidia-xconfig

Second I couldn't see the CUPS interface at http://
localhost:631/. Therefore I reinstalled cups-base
and cups-client and installed cups-image from ports.
After that I edited cupsd.conf in /usr/local/etc/cups
to set the authentication. The command lines are
given below.

# cd /usr/ports/print/cups-base
# make deinstall && make install clean
# cd ../cups-client
# make deinstall && make install clean
# cd ../cups-image && make install clean

Third I tried to install openoffice.org-3 from ports
and the size of /usr was 23GB. It actually was not
little enough. To put it concretely, it was enough
to make openoffice.org-3 but not enough to install
openoffice.org-3. Therefore I temporarily moved some
directories into the home directory and made room
for installing openoffice.org-3 in /usr. The size of
them was about 1.2GB, so the size of /usr, which was
about 24GB, might be enough to install openoffice.org-3.

Finally I am happy to assist you in solving these
various problems on FreeBSD 8.1 amd64.
