simple way to install ubuntu 11.04

First of all ensure u have at least 20 GB of space free in ur hardisk(free means unallocated memory) Once u do that reboot ur system and boot the ubuntu cd from the boot option or change boot preferences from the BIOS. Once your BIOS is configured to boot from CD first, if you have Ubuntu in the drive, you should see the splash screen with a ubuntu written on it. Ubuntu will take a couple of minutes to load up. Just be patient. Select your preferred language. If you have at least 512 MB of RAM, you may want to select Try Ubuntu, as it will allow you to do other things (check your email, browse the web) while you're installing Ubuntu. If you have only 256 MB or 384 MB of RAM, you should select Install Ubuntu. This will give you the same installation screens you see below, but you won't have the rest of the Ubuntu live session running as well. Select your language. There is a new option in the Ubuntu 11.04 and 10.10 installers that asks if you want to install closed sou...

making Ubuntu 10.4 Fast by loading it to ram

What this guide will try to accomplish The guide basically explains how to create a squashfs image out of your existing Ubuntu installation and copy the entire image to RAM upon boot to speed up your OS. I will also go into some detail of how to make your /home mount from a regular hard drive thereby making sure the important information one would wish to save on their machine would remain untouched between boots. A little history I have always been fascinated with the idea of speeding up an OS by the non-conventional way of providing a faster medium from which it runs. I call this non-conventional because I use to think (and I believe many people still do) that just by buying faster and faster processors that my computer would keep speeding up more and more. Although this is the case to some degree, after purchasing my QX9650 a few years back and not seeing as much of a difference as I would have hoped, I realized there had to be something else that was slowing my c...

Scalable Images in Linux

Scalable Vector Graphics (SVG) is a family of specifications of an XML-based file format for describing two-dimensional vector graphics, both static and dynamic (i.e. interactive or animated). The SVG specification is an open standard that has been under development by the World Wide Web Consortium (W3C) since 1999. SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed, scripted and, if required, compressed. Since they are XML files, SVG images can be created and edited with any text editor, but drawing programs are also available that support SVG file formats. All major modern web browsers have at least some degree of support and render SVG markup directly with the exception of any version of Microsoft Internet Explorer (IE) released for the widely used Windows XP. SVG allows three types of graphic objects: vector graphics, raster graphics, and text. Graphical objects, including PNG and JPEG raster images, can be grouped, s...

Basic Files Systems in Linux

minix is the filesystem used in the Minix operating system, the first to run under Linux. It has a number of shortcomings: a 64MB partition size limit, short filenames, a single time stamp, etc. It remains useful for floppies and RAM disks. ext is an elaborate extension of the minix filesystem. It has been completely superseded by the second version of the extended filesystem ( ext2 ) and has been removed from the kernel (in 2.1.21). ext2 is the high performance disk filesystem used by Linux for fixed disks as well as removable media. The second extended filesystem was designed as an extension of the extended file system ( ext ). ext2 offers the best performance (in terms of speed and CPU usage) of the filesystems supported under Linux. ext3 is a journaling version of the ext2 filesystem. It is easy to switch back and forth between ext2 and ext3. xiafs was designed and implemented to be a stable, safe filesystem by extending the Minix filesystem code. It provides the ba...

7 steps to configure your kernel manually

1. Download the latest kernel source package from the website kernel.org. 2. extract the package 3. Use the following command list make mrproper make LANG=LC_ALL LC_ALL=menuconfig ( during the config don't manually select modules till your not 100 percent sure of Wt ur doing . Instead u could use the config file of previous kernel from the boot folder and load it) make make modules_install cp -v arch/x86/boot/bzImage /boot/linuxconfig (if arch is 32bit) cp -v System.map /boot/System.map cp -v .config /boot/config 4. Delete the source files 5. Update grub (verify whether the grub finds two kernel files ) 6. Restart the system 7. If the new kernel works properly delete the previous kernel files from etc , bin , usr folders and update grub again

How to start on with Linux

Having used windows over 17 years now shifting to Linux seems very hard. But is not as hard as it gets if you have the right start .In my opinion the right way to start learning Linux is having a virtual machine software like virtual box by sun and download the latest version of Ubuntu  . The main benefit of working in a virtual environment that your current working operating system is not effected even if Linux crashes. So u can work around your way to learning the OS without really worrying about the problems u might encounter in the \process as even if it does all u need to do is install a fresh version over it. So it gives a good carefree start towards working your way towards learning Linux. As for Ubuntu , it is the most windows type UI that u could get and more over in its functionality is very windows type. In the sense you easily brows through software compatible with your version of ubuntu and install them very conveniently and also use them to get a feel of the wh...
