Everyone is using Thunderbird on MS Windows, Ubuntu Linux and Fedora Core Linux. So, why shouldnt Centos 5.1 be able to install?

1. Download Thunderbird 2 from Mozilla (http://www.mozilla.com/en-US/thunderbird/) or other mirros like (http://mirror.oscc.org.my/mozilla/thunderbird/). I downloaded thunderbird-2.0.0.14.tar.gz to the directory /tmp.
2. Extract the files
3. Open a terminal and login as root to the directory /opt
   

   su -
   cd /opt

4. Copy the extracted forlders to /opt
   

   cp -rf /tmp/thunderbird /opt

5. Install the older library of libstdc++.so.5 (5.1 comes with version libstdc++.so.6)
   

   yum install compat-libstdc++-33.i386

6. Test the Thunderbird as a normal user
   

   /opt/thunderbird/thunderbird

7. Copy the icons to the user wide pixmap
   

   cp thunderbird/icons/mozicon*.xpm /usr/share/pixmaps/

8. When Thunderbird starts, it complains about the mode for /var/spool/mail, as it cannot write to this folder. As root do the following
   

   chmod 01777 /var/spool/mail

Add the application launcher in the panel/menu using the mozicon icon. Only things left is to install other plugins.

In ubuntu hardy heron, wine runs into a new security setting that disables 16-bit applications. When you try to install them, you get an error:

preloader: Warning: failed to reserve range 00000000-60000000

winevdm: unable to exec '--app-name': 16-bit support missing

On ubuntuforums is a solution which actually works:

sudo sysctl -w vm.mmap_min_addr=0

When starting a new program on, for example KUbuntu 8.04, there is a delay of several seconds. This can be caused by SCIM — which is a multi-language keyboard input protocol — not loading.  Check your system logs.  If this is the problem, try as root:

apt-get remove scim-qtimm scim-bridge-client-qt4 scim-bridge-client-qt scim-bridge-client-gtk scim-bridge-agent skim scim-modules-socket libskim0 libscim8c2a

sudo apt-get install nvidia-glx-new linux-restricted-modules-$(uname -r) --reinstall

sudo apt-get install totem-xine libxine1-ffmpeg libdvdread3
sudo /usr/share/doc/libdvdread3/install-css.sh

Problem: error message

play soxio: Failed reading `test.wav': unknown file type `auto'

Solution:

$ sudo apt-get install libsox-fmt-base libsox-fmt-ao

Installs everything you need just for the wave (.wav) format, or use

$ sudo apt-get install libsox-fmt-all

to install all available formats for sox and the play command.

Highly recommended.

For some reason, my fresh Ubuntu install didn’t include all the NFS bits… had to do this:

# apt-get install nfs-common portmap
# /etc/init.d/portmap restart
# /etc/init.d/nfs-common restart

and then I was able to:

# mount 192.168.0.50:/myshare /mnt/myshare
