How to solve the problems related to gdm, OpenOffice, gstreamer-plugins, Compiz, and Bluetooth PAN on FreeBSD 8.0 amd64

It took five days with occasional rests to solve the
problems approximately and it was never out of my
mind if I may be allowed a little exaggeration. I'd like
to express my appreciation for the various websites
referring to the problems mentioned above.

First I used pkg_add to install Gnome2 and dependencies,
deleted gdm from the system, and installed gdm from ports.
Besides that, to change the login background screen, I
replaced background-default.jpg which was in /usr/X11R6/
share/pixmaps/backgrounds/gnome.

Second one of the useful websites referring to installing
OpenOffice for FreeBSD is given below.
http://porting.openoffice.org/freebsd/
The command line to install the package after downloading
OOo_3.1.1FreeBSD80X86_64_install_ja.tbz is given below.

# pkg_add -f OOo_3.1.1FreeBSD80X86_64_install_ja.tbz

Actually I had tried to build openoffice.org-3 from ports
but the size of /usr I adopted was not enough and then
switched the way to install openoffice.org-3 from ports
to using pkg_add.

Third I built multimedia/gstreamer-plugins-all from
ports to play wma and asx files. The command line
to build the package is given below.

# make -i install clean

Actually I had built audio/gstreamer-plugins-lame,
audio/gstreamer-plugins-mad, and audio/gstreamer-
plugins-wavpack from ports but gstreamer-plugins-
bad was missing from the indispensable packages
to listen to BBC World Service and RFI and then
switched the way to build them from picking up
them one by one to building multimedia/gstreamer-
plugins-all from ports. Consequently, I could listen
to the internet radio broadcasting as given above.

Fourth, after building compiz and dependencies from
ports, I went to System->Preferences->Startup
Applications->Startup Programs, added Startup
Programs such as Compiz and Emerald, and edited
their commands. The examples are given below.

Name: Compiz
Command: compiz --replace gconf
Name: Emerald
Command: emerald --replace

Plugin List includes core, dbus, decoration, glib, move,
place, resize, scale, and switcher.

Fifth I referred to the useful website mentioned below.
http://www.mail-archive.com/freebsd-bluetooth@freebsd.org/msg00661.html
I am very much indebted to the website for their useful
suggestion. Reverting to the subject, I added the command
lines as given below to /boot/loader.conf.

netgraph_load="YES"
ng_ubt_load="YES"

Besides that, I added the command lines as given below
to /etc/rc.conf.

hcsecd_enable="YES"
devd_enable="YES"

By default, ng_ubt recognized the bluetooth device, ubt0,
in Thinkpad SL400 and also another bluetooth device, ubt1,
such as BTMicroEDR2X. Then I made connection.sh
according to the website mentioned above for connecting
Bluetooth PAN.

# vi connection.sh
   #!/bin/bash
   ifconfig tap0 create mtu 600
   btpand -a 00:00:00:00:00:00 -d ubt0 -s NAP -i tap0
   #Put the MAC address of our bluetooth device,
   #such as a pocket PC or a smart phone,
   #into 00:00:00:00:00:00
   dhclient tap0
# chmod a+x connection.sh

After pairing the bluetooth device, I could connect
Bluetooth PAN on FreeBSD 8.0 amd64. The command line
to connect Bluetooth PAN is given below.

# sh connection.sh

Finally I will be happy to assist you in solving these
various problems on FreeBSD 8.0 amd64.
