I have already installed ubuntu 11.04 in my notebook. So in this article I am describing method of taking the backup old installation files and doing the fresh install and restoring it.

After boot from live cd, open the terminal and type

#sudo bash

For root login.The type

#mount

command for check the device details

As per the second screen shot you can easily understand that my  older installation is on /dev/sda6 and remainig are windows partition.

ubuntu 11.10 install copying the olde installer file

Then I have created the folder called test and mounted the windows partition on it.

After that I have created folder ‘test1″ for mount the Linux partition on it, Please refer the above screen shot. Then copy the /home/sahab  into the windows mounted directory test.

For the remaining steps please refer the below video file

Blender is professional Open Source 3D modelling suit that’s runs in Ubuntu (which also available for windows).  The latest version of blender is 2.60a.

Blender 2.60 Features
Blender 2.60 come with numerous changes since its version 2.59, here some of feature you can find in Blender 2.60 taken from its official website ”

• Blender 2.60 allow us to place speaker objects in the scene, make an animation and mix down to an audio file.
• Blender 2.60 Includes several changes to the graph editor, dopesheet editor, NLA editor, curves, drivers, constraints, and posing.
• Vertex group modifiers has been added. There are three modifiers can be chosen : one to edit existing vertex groups, one to mix groups together, and another to generate vertex groups based on proximity to other objects
• Blender 2.60 now support non-English language (eg : Chinese

Installation steps

• sudo add-apt-repository ppa:cheleb/blender-svn
• sudo apt-get update
• sudo apt-get install blender

After upgrading the wireless connection didn’t work I thought it was a problem related to the wlan driver.

Finally I have followed below steps for resolving the issue

Open the terminal

Alt+F2 type gnome-terminal

then run the below command

$sudo apt-get remove –purge network-manager

uninstalled the networkmanager

$sudo apt-get install wicd

Installed the wicd for fixing the issue.

Open the terminal

enter your root password to place the nebula in your grubs boot images….

now were going to remove the old desktop base script and replace it with a more stellar one….
do this block of code to remove.

sudo su

write new script 4 background on boot 

cat > /usr/share/desktop-base/grub_background.sh << EOF
WALLPAPER=/usr/share/images/grub/nebula.jpg 
COLOR_NORMAL=light-green/black
COLOR_HIGHLIGHT=green/light-gray 
EOF 
update-grub 
exit 

and press return to exit god mode, reboot to test.... it is a 1280x1024 image, and might require editing
a file i already edited to change the menu size to fit the image.but for the most part this was a
nagging hidden system when trying to edit /etc/grub.d/05_debian* only to have a strange variable
over ride what you set. and this is what you get when bob punishes your boot loader settings

I have installed the RHEL 5.7 (64 bit)using all the development tools and libraries.  Partition is default partition.

Basic installation is straight forward.

Click here for download the Oracle 11g Express Edition. Now oracle releasing the 64 bit version only.

After the download Unzip oracle-xe-11.2.0-1.0.x86_64.rpm.zip.

#unzip oracle-xe-11.2.0-1.0.x86_64.rpm.zip

This will create the directory Disk1. Change to the Disk1 directory:

# cd Disk1

#ls

Linux Basics

sudo set-language-env -E – Default Language

sudo dpkg-reconfigure console-setup – used to reconfigure the default language

For example if you need to chanage the default language to German, run the above command and choose your default language.

Use the command “sudo visudo” to edit the file. Now look for the line “# User alias specification” and add a list of users as follows:#

 User alias specification
User_Alias USERS = user1, user2, user3

Now look for the line “# Cmnd alias specification” and add a command list as follows:

# Cmnd alias specification
Cmnd_Alias SHUTDOWN_CMDS = /sbin/shutdown, /sbin/reboot, /sbin/halt

Now look for the line “%admin ALL=(ALL) ALL” and add the command which will let USERS give SHUTDOWN_CMDS without a password

:%admin ALL=(ALL) ALL
USERS ALL=(ALL) NOPASSWD: SHUTDOWN_CMDS

Now those specified users can use the commands “sudo shutdown”, “sudo halt”, and “sudo reboot” without being asked for your password.

EDIT: By the way, the reason that these commands can’t be used by normal users is that Linux was designed as a multi-user system. You don’t want one user shutting down the system while others are using it!
