Broadcomm 43xx on Karmic Koala

2009-11-13T15:10:00.003+07:00

Thanks to Karmic which has made me come back and wrote somethings down here.
I found my first case, there was a netbook which run smoothly on JJ. But when i installed KK on it, the wireless did not do anything....hmmm

so....here we go:

Open terminal, make sure that your wireless is "Broadcomm 43xx" by typing sudo lspci
Insert Ubuntu 9.10 LiveCD to CD-ROM drive.
Type these command below

sudo apt-cdrom add
sudo apt-get install dkms patch fakeroot bcmwl-kernel-source

Restart computer.
Go to System - Administration - Hardware Drivers; Broadcomm BCM43xx wireless chip had been detected
Now it's time to set the wireless connection

Joomla! - Liberate the Authors

2009-08-20T21:15:00.017+07:00

To hack the Joomla! 1.5.x ( to open the gate for the authors ), is to change the following two files ( the hack has to be applied to any future upgrade of the core )

File 1 is ...components\com_content\controller.php
Go to Line 229 and comment out some lines to stop the wrong message coming up on save:

// if ($access->canPublish)
// {
// Publishers, admins, etc just get the stock msg
$msg = JText::_('Item successfully saved.');
// }
// else
// {
//  $msg = $isNew ? JText::_('THANK_SUB') : JText::_('Item successfully saved.');
// }

File 2 is ...components\com_content\models\article.php
Go to line 332 to change the zero value:

// For new items - author is not allowed to publish - prevent them from doing so
$article->state = 1;

The Authors are Liberated !

Nautilus Scripts

2009-03-05T09:43:00.007+07:00

Started from here, talked about Send To feature ( this feature is famous in Ms. Windows -- i think ) , i just realized that i have missed another simple thing !!
I found something in wiki and something in unleashed.

If you need Copy-To script :

#! /bin/bash
location=`zenity --file-selection --directory --title="Select a directory"`
for arg
do
if [ -e "$location"/"$arg" ];then
   zenity --question --title="Conflict While Copying" --text="File ""$location"/"$arg"" already exists. Would you like to replace it?"
   case "$?" in
      1  )  exit 1 ;;
      0  )  cp "$arg" "$location" ;;
   esac
else
   cp "$arg" "$location"
fi
done

If you need Move-To script :

#! /bin/bash
location=`zenity --file-selection --directory --title="Select a directory"`
for arg
do
if [ -e "$location"/"$arg" ];then
   zenity --question --title="Conflict While Moving" --text="File ""$location"/"$arg"" already exists. Would you like to replace it?"
   case "$?" in
      1  )  exit 1 ;;
      0  )  mv "$arg" "$location" ;;
   esac
else
   mv "$arg" "$location"
fi
done

just copy the script to your text editor and save it to
~/.gnome2/nautilus-scripts/
But, don't forget one more thing;
your script must be executable by typing
sudo chmod a+x ~/.gnome2/nautilus-scripts in Terminal.

You can get Send-To script here
Open your Nautilus and the scripts will be there when you right-click on something ( press reload button if you didn't see any )

Done !!!

HP LaserJet 1020 on Hardy Heron

2009-03-05T09:13:00.008+07:00

Frankly, i never know that this printer can't directly work if we installed it in HH by using direct connection. Otherwise, i always use this printer through network and it works totally well.

When i looked at this problem in google... i was shocked that this issue is there and it was an error from the bundled driver of HH ( i am totally late in figure this out )
So....the solution was I have to replace the bundled driver !!

open Terminal
type sudo bash
apt-get install build-essential { install build-essential }
wget -c http://foo2zjs.rkkda.com/foo2zjs.tar.gz
{ to download the driver }
tar zxvf foo2zjs.tar.gz { extract the downloaded driver }
cd foo2zjs { change the working directory }
make { start to build the driver }
./getweb 1020 { get additional firmware }
make install { install the driver }
make install-hotplug { install hotplug }
make cups { restart cups }

done !! and Great Thanks to the resources

Simple anonymous ftp server

2008-12-11T09:49:00.004+07:00

This time, i just wanted to create an ftp server to share some "read-only" files. If i put these files on a public samba shared, it will easily to be changed. It will not be good if you change a teaching schedule by yourself...not by the authorities.
Next example can be a master report file or master forms.

I just did :

install proftp :=> sudo apt-get install proftpd ucf
activate the anonymous section on the /etc/proftpd/proftpd.conf
restart proftp :=> sudo /etc/init.d/proftpd restart
Done !!
from web browser :=> ftp://servername/

When i did not activate the anonymous section on proftpd.conf, it seemed like we can open all home folders of that server ( of course this is BAD !! ) even the ftp asked for a password.

Missing fstab..............

2008-11-21T15:06:00.006+07:00

I slipped on my own script, my fstab erased.......
It only contain a line to mount CD-ROM....wakakakaka

After googling, i found this
By reading this article, i assumed that we have to know the UUID for each drive, especially for the / and swap ( for windows disk can be done later )

First, used blkid from terminal by typing sudo blkid
here is the output

/dev/sda1: UUID="2C28F09028F059F2" TYPE="ntfs"
/dev/sda5: UUID="2C82313F7F68F931" TYPE="ntfs"
/dev/sda6: TYPE="swap" UUID="f2ea4d4c-ef3f-49dd-9f4a-ea140e93c69e"
/dev/sda7: UUID="ced3011b-4675-4790-8065-d8e0601f6bf1" TYPE="ext3"

I just have to copy / and swap UUID and paste to my (new)fstab,
after some editing, it looks like :

/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0
//192.168.1.100/shared /media/x cifs rw,uid=root,gid=root,file_mode=0777,dir_mode=0777,noperm 0 0
UUID=ced3011b-4675-4790-8065-d8e0601f6bf1    /    ext3    relatime,errors=remount-ro    0    1
UUID=f2ea4d4c-ef3f-49dd-9f4a-ea140e93c69e    none    swap    sw    0    0

After reboot, my system is back to normal
( I applied this to Hardy Heron, Intrepid Ibex and Mint Elyssa )

Mass rename and mass resize using gThumb

2008-11-11T12:45:00.000+07:00

Sometimes we will feel reluctant if we want to rename so many files. But actually, it can be done once for many files at the same time. I was tried it by using gThumb

First, of course we have to install gThumb
Open terminal then type sudo apt-get install gthumb

Next, open gThumb and go to the folder which we will work for
The left panel will be the tree panel and the right panel will contains the files from a folder
After we meet the folder, choose some/all pictures which we want to rename from right panel
do right click, then choose rename, below dialog will appear then you can rename them up ( don't forget to click rename button )

Then, in order to do mass resize,
Go to Tools - Scale Images ( below box will appears )

Beside those two, we also can do mass rotate and mass convert by using gThumb

Combine some pdfs into one

2008-08-05T17:38:00.003+07:00

This started by downloading some e-books from our national education government sites which consists of e-books of some subjects which parted into chapters.
I was just thinking that "could they just be combined into one file only ?"

Based on this article, i got my answer : we can !!

First, download some files from terminal by typing ;

sudo apt-get install gs pdftk

Second, execute those pdfs

gs -dNOPAUSE -sDEVICE=pdfwrite -sOUTPUTFILE=combinedpdf.pdf -dBATCH 1.pdf 2.pdf 3.pdf

Which OUTPUTFILE=the name of combination file
1.pdf 2.pdf 3.pdf are the name of the partial pdfs

After you run the above command, a new PDF file called combinedpdf.pdf will be created with your individual files merged according to the order that you have you listed.

Samba File Server

2008-06-11T13:55:00.007+07:00

Now, i re-install one of the server to be pointed as a fileserver, which will stores files from the users here. I installed samba on Ubuntu Hardy Heron server edition

We will concentrate on /etc/samba/smb.conf ( samba configuration file )

The condition that i like to make are :

one public shared folder
some folder which can be access base on that folder password

Base on the above conditions, so :

sudo mkdir /home/shared { create a shared folder for public }
sudo adduser --home /home/source source {create source user}
sudo adduser --home /home/filing filing {create filing user}
sudo smbpasswd -a source {smbpasswd for source}
sudo smbpasswd -a filing {smbpasswd for filing}
sudo nano /etc/samba/smb.conf

below is the content that i adjusted of my smb.conf file;

[global]
workgroup = workgroup_name
netbios name = citserver { this computer name for network }
host allow = 192.168.1.0/24
server string = %h (Ubuntu Samba Server)
security = share
smb passwd file = /etc/bin/smbpasswd
dns proxy = no

[home]
read only = no
browseable = no

[shared]
path = /home/shared/
comment = X Directory
public = yes
read only = no
browseable = yes

don't forget to restart the samba service :==> sudo /etc/init.d/samba restart

Now, you can access samba shares from the clients
For Windows :==> type \\citserver\foldername on explorer bar
For Linux :==> smb://citserver/foldername on nautilus bar

For more and details info :==>

Radeon X1550 or RV505

2008-04-17T13:23:00.022+07:00

I got six new computers which specifications are :

MB : MSI K9AGM3-FIH ( sound : Azalia / ALC888 )
VGA : GigaByte GV-RX155128D-RH ( RV505 )
Proc : AMD Athlon64 X2 4800+
RAM : V-GEN 1GB
HD : Seagate SATA 80GB

Installing Edubuntu Gutsy Gibbons on this unit need an extra patient and search, since i can not find the driver for the display which identified as RV505. I also can not find the driver on ATI driver site. After some times.....here is the way !

If you are trying to install Hardy,
the installation will be flawlessly
you just need to Enable ATI in Hardware Drivers
( previously recognized as Restricted Drivers )
xorg-driver-fglrx will automatically installed
finish the process by reboot
then install compiz....set it....run it

First of all; boot from Edubuntu liveCD and when the installation menu appears; press F6 and it will display Boot Options command like;

file=/cdrom/preseed/edubuntu.seed boot=casper/initrd.gz quiet splash --

erase "quiet splash --" by pressing backspace button, so it became;

file=/cdrom/preseed/edubuntu.seed boot=casper/initrd.gz

then press enter

The processes will run and will end up with no GUI but a blue screen with a log info printed out
press OK and then you will see the screen displayed something like :

..
..
* Running local boot scripts (/etc/rc.local)

and with the cursor keeps blinking

then press ctrl+F2 to bring you to the prompt to type

sudo dpkg-reconfigure -phigh xserver-xorg

choose vesa then ok
choose the screen resolution then ok

the monitor will blink again for a while and bring you to login window.....just let it login in 10seconds automatically (if you are back to the prompt, type startx , later on you will be asked to press ctrl+F7 for the default GUI )

Now you can install edubuntu

When the installation finished, restart the computer and login to edubuntu.

We have to update the system
1. go to system - administration - software sources
2. after that close it and reload it
3. update the system from system - administration - update manager

Then we can work with the display ( still vesa now ) to activate compiz
1. go to system - administration - restricted drivers manager
2. enable the ATI accelerated graphic driver
3. it will automatically download xorg-driver-fglrx
4. open terminal ( applications - accessories - terminal )
5. type sudo gedit /etc/X11/xorg.conf
6. Find Section "Extensions", change "Composite" "0" to "Composite" "1"
7. save and exit the editor ( ctrl+s and ctrl+q )
8. still in terminal, type sudo apt-get install xserver-xgl
9. then type sudo apt-get install compizconfig-settings-manager
10. then sudo reboot
11. after reboot, go to system - preferences - appearance
12. go to visual effects tab
13. change to custom ( it will blink and done.....you can choose it now )
14. click preferences to set the compiz effects
15. finish

Mapping a windows shared

2008-04-16T15:30:00.003+07:00

When we had a computer which run as a file server in a network, sometime or maybe, we would like to map it to make easy to be called ( in windows, we can map as "X:\" or Y:\ or else ). Here we have a linux server which has a public shared folder which shared as windows shared.

What about in Linux(Edubuntu) ?
In Edubuntu w can go to Places - Connect to server
I used to use windows shared, server = citserver and folder = shared then click Connect
It ended up with an icon named "shared on citserver" on the desktop

This map, caused me problems some times ago, students can not save the firefox files directly to it. And some applications also can not save to it directly. The exceptional is OpenOffice, it can !

In order to make all applications can save to the server, first, open terminal

sudo apt-get install smbfs
sudo mkdir /media/x
sudo gedit /etc/fstab

in fstab, insert

//citserver/shared /media/x cifs rw,uid=root,gid=root,file_mode=0777,dir_mode=0777,noperm 0 0

then

sudo mount -a

Now, you will have a mapped drive named "x"

Addition : ( requested by doniepos )
I used this x for making an intranet repo ( combined with my previous post about own customized repo ) In my /etc/apt/sources.list, i put

deb file:///media/x/Linux repo/

With a good combination with cron, this intranet repo is automatically update weekly

Play more with compiz

2008-01-25T11:33:00.000+07:00

In continuing my war with my friend ( edubuntuGG vs pclos2007 ), i spent some time of mine to knock him down. And i did it ( for this time......seems like this war will never end....heheheh )

Ohya...let me tell some about him, he was installed pclos some times ago and while the rest of teachers here moved to edubuntu, he sticked on his pclos. I honourly salute him since he was not from IT background and struggled alone in using pclos by himself. His pclos desktop had been crashed and burnt so many times because of the compiz setting and he kept on it.........good job my pclos ranger........

Back to play more with compiz, actually i just added some additional effects which couldn't be found in basic compiz installation.I am succeed on fireflies, snow, cube snow globe, cube atlantis, 3d windows, autumn, failed on stars, freewins, anaglyph. Not yet : screensaver, freewins, wallpaper, tile and photowheel.

firstly, you have to install some additional packages, open terminal and

sudo apt-get install compiz-bcop compiz-dev build-essential libxcomposite-dev libpng12-dev libsm-dev libxrandr-dev libxdamage-dev libxinerama-dev libstartup-notification0-dev libgconf2-dev librsvg2-dev libdbus-1-dev libdbus-glib-1-dev libgnome-desktop-dev x11proto-scrnsaver-dev libxss-dev libxslt1-dev libtool libgnome-window-settings-dev gitweb curl autoconf automake automake1.9 libtool intltool libxslt1-dev xsltproc

next, create a compiz folder --> sudo mkdir -p ~/compiz/

then get the packages for additional effects, ( all files will be on /tmp )

wget -O /tmp/3d.tar.gz 'http://gitweb.opencompositing.org/?p=fusion/plugins/3d;a=snapshot;h=db3c51d6c5c0df268fc1ec29a4264ef3d21dbbb3'

Play with compiz

2008-01-25T10:27:00.001+07:00

I made this article, based on my funny experience which i had installed compiz but i don't have any idea how to play the effects. I am using HP Presario M2258 ( Intel Centrino 1.73GHz, 512MB RAM, Intel Mobile 915GMdisplay adapter )

In dealing with compiz, we have to

Have a computer with Linux installed ( i used Edubuntu )
install the compiz : sudo apt-get install compiz
be creative !! ( i missed this before..... )

Next : go to System - Preferences - Advanced Desktop Effect Setting
or
from terminal, type : ccsm

The compiz setup windows will appear and you can activate or de-activate any effect based on your desire.

Tips :
always activate resize windows
beware of opacify ( i turned this off )
Super button = the button which has windows logo

Here is some clues :

Desktop cube : add the workspace to 4 and activate 3d cube, then set the opacity as you wish which can be found on transparent cube tab
Rotate Cube : Activate this and set some perimeters ( speed, zoom, timestep, etc )
Activate animation and set the effect for each windows behaviour
activate wobbly window
activate cube caps and set the picture for top and bottom of the cap
activate expo and see the result by pressing Super+E

play on effects : ( activate the related effect first )
Paint fire on screen : on = Shift+Super+button1, off = shift+super+c
Water Effect : shift+F9
Shift switcher : super+tab ( turn off ring switcher first )
Ring switcher : super+tab ( turn off shift switcher first )
3d rotate desktop : Ctrl+Alt+Button1+move or Ctrl+Alt+Drag the mouse

Last thing : after you activated an effect, please find the action key, it usually under the actions tab under the binding menu ( i missed this before, and i found this out after my friends came to me and show me his PCLOS compiz........he declared a war....i have to fight back.......now we still have it )

Kambing : my best edubuntu repository

2008-01-24T13:06:00.000+07:00

Repository is very important for me in improving my linux knowledge. I used edubuntu and everytime it released, i just downloaded the live cd only. After that, i tried to add with some packages which i needed most. Since i live in Indonesia, it's hard to get the repository from outside servers. The connection is better at night. I ever re-installed my unit and tried to update it all night long. And i am sure that there is another way to prevent this.

By the time, i can make local repository. and now i anchor my repo to "kambing" server. It faster than before, even on the busy hours. I can get at least 1Kb/s rate in a full loaded traffic, but i also ever get 60s Kb/s connection.
Based on this link, I just did few steps to switch my repo to kambing server.

open terminal
type : wget http://arsip.ubuntu-id.org/berkas/sources.list.kambing
sudo mv sources.list.kambing /etc/apt/sources.list
sudo apt-get update

That's it.......now i can install or update from kambing with a faster connection.

Kambing : PCLOS 2007 repository

2008-01-24T11:54:00.000+07:00

I have a friend who used PCLinuxOS 2007 and i am happy for him since now he can make his desktop became cube, rotate it and also burned. One day he asked me : can i have a link of pclos repo from Indonesia ? because, it took long time to get the repo from abroad servers.

I tried to find how to switch pclos repo to kambing ( this name is so familiar to Indonesian Linuxers ), and then i made it.

Here is the steps :

open super user terminal
type --> vi /etc/apt/sources.list
go to the last line and add below line to it
rpm http://kambing.ui.edu/pclinuxos/apt/ pclinuxos/2007 main extra nofree kde
put # on the rest of the other lines of repositories
save it and close it ( esc, ZZ )
type --> apt-get update
done

now, my friend can install or update from kambing which is faster !

Edubuntu : Own Customized Repository

2007-12-21T13:19:00.001+07:00

I had a problem when I installed Edubuntu in a new unit, I have to download some additional packages which could not be found in bin-1 and bin-2 CDs ( like NTFS, Gstreamer, XMMS, K3b ). I kept doing this time to time. Can I make it simpler ? Should I spend my time on this repeating activity ?Can I just download the packages once ? These questions were kept asking by myself to myself.

Meanwhile, I have to start to socialize Linux, Edubuntu especially to my students. I do not want my students keep thinking that installing Linux is miserable. I want them able to install Edubuntu in the easiest way.

After sometime passed by, I found a link to make local repository here
I tried to do like what the link instructed and I succeeded in re-installing a unit. From this point, I tried to expand it by questioning myself : Can I make a repo CD consist of (almost) latest update and my own desired packages ?
Now I can answer it : yes I can..........Now I can make a CD consisted of some programs which I always(will) use and also (almost) latest updates.

Repo Making :

First; I have to install a package called dpkg-dev in my laptop, so go to Application – Accessories – Terminal and type sudo apt-get install dpkg-dev. System will download 2 files which are dpkg-dev and patch in order to install dpkg-dev.

Second; collect the packages from bin-2 CD ( add-on CD ) which I wanted to be installed in other computers. Or in my case...packages that I wanted to be distributed. I took qcad, inkscape, tuxpaint, tuxtyping, screem, dia and put those packages in /home/oedha/Desktop/repo

Third; take the updates packages from the most up to date unit. To do this, go to /var/cache/apt/archives of this up to date unit. Copy all *.deb files to another place. Then, put all these deb to /home/oedha/Desktop/repo

Fourth; download and get the packages of some additional programs and also put these to /home/oedha/Desktop/repo. Now this repo folder consists of 248 deb files ( NTFS, Gstreamer, XMMS, K3b, dpkg-dev, patch, ndiswrapper, compiz, kiba-dock, qcad, inkscape, tuxpaint, tuxtyping, screem, dia, Amaya, ktoon, synfig, ssh, the last update was Dec 20, 2007, )

Fifth ( make the Packages.gz ) :

go to Application – Accessories – Terminal
type : cd /home/oedha/Desktop
type : sudo dpkg-scanpackages repo /dev/null | gzip -9c > repo/Packages.gz
wait until it's finished and it will report me : Wrote 248 entries to output Packages file.
Now, I can find a file named Packages.gz in repo folder ( total = 249 now )

Sixth; now we can burn this folder into a CD. I named this CD as “Add-Ons”. I also put some additional folders on this CD which were AVG for Linux + updates, Windows installer ( gimp, amaya, openoffice, inkscape, tuxpaint ), flashplayer, and direction files.

( This repo folder also can be shared wihout using CD ; shared folder, flashdisk )

Repo Using ( in other units ) :

Install a fresh Edubuntu or can be a unit which not up to date or can be a unit which will install a program which can be found in the Add-Ons CD
Insert Add-Ons CD into the CD tray
go to System – Administration – Software Sources
Click on Third Party Software tab then click add CD-ROM button
Click OK button then type the CD name : Add-Ons
Click OK then click Close ( see picture below )

Go to Ubuntu software tab, Make sure that there's no box been checked and then close it. You will ask to reload the package, click reload button
go to System – Administration – Update manager
click on install update button
wait until it's finished and then close it ( now it's updated )
go to Applications – Add/Remove
search : ntfs show : all available applications
click apply changes ; wait until it's finished, then click close button
you have installed NTFS configuration Tool
do step 12 and 13 for the next program

For you who did not use CD, you can do below steps

copy repo folder from network share or flashdisk to Desktop
go to System – Administration – Software Sources
Click on Third Party Software tab then click add button
type : deb file:///home/oedha/Desktop repo/
Click OK then click Close
Continue with updating the system and install programs

Hooray.....now my plan is ready to be implemented. I asked my students to prepare 3 blank CDs if they want to install Edubuntu; one for Edubuntu-live, one for Gparted and the third is “Add-Ons”. Previously I asked them to prepare 4 to 5 CDs. Now they just prepare less CDs, easy installation, additional programs and do not have to be online at home.

Finally, I can save bandwidth ( I also set proxy cache in the Router server up to 20GB to prevent repeated download from clients ), fastest process and I can enjoy in installing Edubuntu !!

I hope this article can help you................

Why don't we remote it ?

2007-12-07T10:45:00.000+07:00

Sometimes we can not physically touch a server or a workstation. But, it does not mean that we have to wait until we have a chance/time to touch it. Why don't we remote it ?
To remote a unit, we have to install ssh first. Before using Gutsy Gibbon, i found out that i don't need to install ssh since it was installed by default. But, when i used Gutsy, i met problem i can not remote a unit, so, i have to install ssh after GG installation

How to install ssh ?

Go to System - Administration - Synaptic
search for ssh
check on ssh then click apply button

go to Applications - Accessories - Terminal
type : sudo apt-get install ssh

I like to remote a unit using PuTTY or Remote Desktop (vncviewer)

PuTTY is a free implementation of Telnet and SSH for Win32 and Unix platforms, along with an xterm terminal emulator. It is written and maintained primarily by Simon Tatham.

For more info --> go to PuTTY site and wikipedia
To download it --> http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
For Edubuntu --> sudo apt-get install putty

To use PuTTY : go to Applications - Internet - PuTTY SSH Client, enter the IP address of the machine that we want to remote. You will be asked for the username and password for that machine.

Remote Desktop; this way can be done from Terminal, before doing this, we have to set the remote desktop setting on the target unit(s).

For example: i want to remote 192.168.100.100 from my laptop, so first i will go to 192.168.100.100 unit to do these;

go to System - Preferences - Remote Desktop
check on the sharing and security options base on my need
click close button

Back to my laptop;

go to Applications - Accessories - Terminal
type : vncviewer 192.168.100.100:0 or vncviewer tester:0 (unit name)

From the above picture, i can view and control the target desktop. ( password required )

Happy Remote !!

Edubuntu Package installation

2007-12-07T10:23:00.000+07:00

*.deb package installation
These files are Debian packages. The package files associated with Edubuntu. You will need administrative privileges to install a .deb file.

To install a *.deb :
- open the package location; double-click on it. or
- from Terminal; type : sudo dpkg -i package_name.deb

To uninstall a *.deb :
- open synaptic; deselect it then click apply button. or
- from Terminal; type : sudo dpkg -r package_name

*.rpm package installation
Another type of package files is Red Hat Package Manager files which have the .rpm suffix. It is not recommended to install these on an Ubuntu system. However, if absolutely necessary, an .rpm file can be converted to a .deb package using alien

To convert *.rpm to *.deb
Install the alien package; open synaptic, search for alien and select it, click apply button. or from Terminal; type sudo apt-get install alien
In a Terminal, type : sudo alien package_file.rpm
The converted package can be used like normal .deb

Tarballs installation ( .tar, .tgz, .tar.gz or tar.bz2 )
If there is no native Ubuntu package available in any of the Ubuntu repositories, you can use the command line to install or uninstall the tarball file. Tarballs often contain the source code of the program, and need to be compiled in order to be used. Compiling programs requires some packages that are not installed by default. You can install these all at once by installing the build-essential package.

Extract the tarball; double click on it then click extract. or from Terminal; type : tar xfvz tarball_name
Then open the extracted, find the the instructions that come with the package. The instruction can be found in README or INSTALL file. Follow that instruction to compile and install a tarball file.

*.run installation
Sometimes you may need to install software which has been packaged as a .run file. These files contain the software and a small program to install the software.

Find the *.run file from file browser
Right-click the file and select Properties
Cclick on permission tab, check on Allow executing file as program then click Close button
Double-click the .run file. A dialog box will appear
Click Run in Terminal button to run it.
A Terminal window will open. Follow any instructions on-screen to install the program

To install a program :
We can do it package per package, from Add/Remove, from Synaptic or from Terminal

For package to package; make sure that all packages were met the dependencies of that program, then install the package one by one based on the dependencies sequence.

For Add/Remove;

go to Applications - Add/Remove, type the program name and show : all available applications
check the desired program
click apply button

For Synaptic;

go to System - Administration - Synaptic packages manager
click on search and type down the program_name
check the desired program
click apply button

For Terminal; just type : sudo apt-get install program_name
