Linux has very little "eye candy". There are many different things that can be done to the system to have an interface like the graphic effects. It's not necessary to actually do anything important, but they make the desktop look great. In your Ubuntu install, there are ways to improve how it looks and works better visual effects.

By default Ubuntu has some visual effects on the system. Go to System> Preferences> Appearance. Click the Visual Effects tab at the top of the screen. This will give you several options with no effects, normal activity, or additional effects. You must have a graphics card that handles the added effect if they are used.

If you want to be "spinning cube" you've seen on YouTube video, you need to install Compiz Fusion from the repository as well as Compiz Config. Start the configuration program to enable or disable the action. Turn on Compiz and enjoy all the effects that this program can do. It should be more than enough for everyone.

You might notice that other Ubuntu users seem to have a completely different look on their PCs. Some have taken the custom theme to make things look different. At other times they are using different interface altogether. There are KDE and XFCE version of Ubuntu and Gnome, which is the default one. If you want your desktop to look like these, you must install on your system desktop, or you can reinstall Ubutnu with Xubuntu or Kubuntu.

One thing that happens to many users is to be noted that the performance will go down a bit when you use too much influence. This happens on older machines. If it is causing problems on your system, you may have to disable some of the features of Compiz so that your computer will be so slow.

This article is about dual-booting Ubuntu Linux for-8, 04 (Herdy Heron) and Microsoft Windows XP;. Ubuntu, which is already installed in the system

to manage the dual-boot should boot manager. In Windows, we know that as a bootloader and Ubuntu it is called GRUB.

When we install XP after Herdy Heron, it will completely overwrite GRUB with its boot manager. Unfortunately, until now, Windows is not good enough to deal with this kind of situation or they simply do not want their users the experience of other operating systems.

so that after installing XP you will only see the XP startup screen, it will be Linux. Now we have to reinstall grub to see them together. To do this, you will need to install Ubuntu OS CD. Insert it into the CD ROM and restart the computer. Select your preferred language. Select Try Ubuntu without any change to your computer. This will lead you to boot up the live session.

Now go to Applications -> Accessories -> Terminal. Then type "sudo grub" and press Enter.
"> grub" This is what you will see and will keep seeing until you finish a tough session.
Now just type "find / boot/grub/stage1" after "> grub" and it will appear rough.
You'll find something like "(HDX, Y)", where X and Y be two numbers. If you are a newbie, you need to know immediately what this means.
For example, it is "(hd0, 1)" It should be "> grub (hd0, 1)" look.
Now enter "root (hd0, 1)" It should be "> grub root (hd0, 1)" look.
Now type "setup (hd0)" It should be "> grub setup (hd0)" look.

if everything goes right you will see some lines with success.
Now you can type "stop ".

One interesting feature about Linux is that you can install it on any hardware you like. There are no hardware limitations due to licensing and other commercial operating systems. Since it can install on whatever you want, people have developed a way to run Linux on other hardware. One option you have is that Ubuntu, a popular Linux distribution and install it on a USB memory stick.

You will need to have installed Ubuntu and a USB flash drive with at least 4 gigabytes of memory. Realistically you probably want more than that, but it will work with just four. Click on System Administration and then run a USB Startup Disk Creator. Follow the instructions and correct your Ubuntu distribution you use will be installed on a USB flash drive.

You take this stick and use it to boot into Ubuntu from the drive sama.Cijelog operating system will work from that. Put it in your computer before you boot up and you should get the choice to either boot from a USB device or go to your normal operating system. Older computers may need to change the BIOS settings for booting from a USB device before the hard disk.

This has some interesting uses. First, when you're locked out of your operating system because it is damaged. Many times, trojans and other malware can destroy and operating sustav.Prednost boot Ubuntu so that you can still access the files on your computer even if the normal operating system will not boot.

Another advantage is that you can use to boot up the computer that you are not sure they are safe and may have spyware. When you sign up for important accounts such as your bank account, you must be sure that the spyware and keyloggers are not on the machine. Your USB Ubuntu will not have these malware meaning of your accounts and keys will be safe.

can put the entire Ubuntu operating system on a small USB drive. Learn how to do and what you can do with technology.

Regular Ubuntu Linux user and the (lack of use) root user

When you install Ubuntu, create a user, the "first" and users can also create multiple users if necessary. When you create a "first" user and assign this user password - and this is one very important

You need to log on your desktop (the Linux GUI login prompt) as "ordinary" (non-root) user - and this password must also be able to do the equivalent of the application as the root user -. When working on a Linux prompt, terminal emulation window on the desktop

By default, the root of usage is not "enabled" (not available) in Ubuntu so i can not log in as this user - which is an innovative thing - how to stop anyone from applications on the desktop as this user - they should be never be done

an example of running Linux sudo command - to get started as root user

by typing in: sudo-i and press Enter to change to a "regular" users to act as ( equivalent to ) root user in Ubuntu (and variations or derivatives such as Kubuntu - see more on that below further ).

, and then give the password the first user who created the system. After running the Linux sudo command, a quick change from a dollar sign on the number or hash mark (press Shift 3). For the "return" to work as a "regular" way to run a command by entering the name of the command and pressing Enter.

The Linux version has its own "derivatives" (variations), and many of them end in "Ubuntu", such as Kubuntu.

Linux Commands Training Tips: " K " in K is ubuntu abbreviation for " K de" - it is " K " in " K dE" for K DE desktop.

Ubuntu distro uses the GNOME desktop by default and Kubuntu uses the KDE desktop by default.

Ubuntu Linux and it's derivatives are some of the few distributions that require using the command sudo-i option as shown above - as opposed to using the commands - "dash" option and then entering the root password users.

When you use your computer, especially for work or school, it is important to be efficient with the system, so you can get more work done quite a bit faster. In Ubuntu there are a few tips that should help accelerate the use of computers.

The first is the keyboard shortcuts. Many of the standard shortcuts such as Control + C to copy and Control + V to paste the same as it is in Windows. If you have not learned their basic shortcuts like this, they are memorized. They are designed to be easily used by left hand while the right hand uses the mouse.

When you use a program that you used to spend hours during the week, take 20 minutes and memorize all the keyboard shortcuts for tasks you most. This will reduce the time it takes to click through menus with the mouse.

Alt + F1 opens up your applications menu to launch applications faster. You can then choose the ones you want to open.

Alt + F2 opens a small window. In this start typing the name of your programs and icons below will appear narrowing down the list.

Consider using Gnome Do. This is the kind of quick start that also has a series of time-saving features. Installation of the repository and use Super + Space to start it.

If you use the same applications every day, you can all back the way you left them when you restart your computer. Go to System> Preferences> Startup applications. Go to the Options tab and check the box so that the computer remembers your open programs.

to keep an open mind and always try to be proactive about ways of doing everything as efficiently as possible. For the new program, it could take a few minutes of learning, but it pays in the long run.

One problem that many people have about trying out a new OS is that they do not want to clutter your currently installed operating system, which is usually Windows. The idea of ​​messing up and losing all your Windows files in many places the fear that makes them not want to try new things such as Ubuntu. Fortunately there are ways to try Ubuntu without even touching Windows.

First of all, download the Ubuntu ISO from their website. These instructions will actually work for any Linux distribution that provides an ISO file so that it can be repeated with other versions.

Once downloaded, burn the ISO to a CD as an image, not the data on the disk. Put the disc into the CD ROM and reboot. Most computers will boot directly from CD first. If yours does not, you have to figure out what button to press to get the BIOS and change the settings so that the CD ROM boots before the hard disk.

After starting the computer boot from the CD, you will see the Ubuntu start screen. Just press Enter here. All you do is review OS and not install anything. Do not worry about the installation, because it will be a series of buttons to get to the actual point of installing the operating system so that it can not be done on the accident.

If you know how to work with virtual machines, you can boot a virtual machine with an ISO file in the attached CD and run the Ubuntu ISO the same way, but almost.

Note that the CD experience will be a little slower than when it is actually installed. This is because it takes longer to load data from a CD than when it is installed on your hard disk.

operating systems like Ubuntu to provide users a way to experience the operating system without installing it on Windows. There are ways of keeping the operating system on a CD to test the system.

Many people are intrigued by the idea of ​​using another operating sustavu.Najveća concern is that in trying a new operating system Windows installation somehow going to be messed up. There are several ways to try new operating systems such as Ubuntu without touching Windows.

you can try Ubuntu from the Live CD.

One option is to download and burn what's called a Live CD. If you do not know how to download and burn this CD, you can always order a free CD from Ubuntu, or sometimes no one at computer stores.

Once you have this CD put it into the computer and turn off your computer. When you turn it on again you will see a screen asking if you want to install and try Ubuntu. Do not worry about the word "install" because it can not accidentally install it, if not želite.Cijelog operating system will run from a CD allowing you to check it out without messing up windows.

You can also try Ubuntu in a virtual machine.

Another option is to start the virtual machine. It is a little more complicated. Download a free program called Virtual Box. Once it is open and running to start a new "machine". Set it to at least 512 Megs of RAM, 32 Meg video RAM, and arbitrarily set the amount of disk space, because it does not matter now.

then add the ISO image you downloaded from the Ubuntu CD-ROM in the virtual machine and boot up.

This will let you play around with Ubuntu and boot into Windows without installing anything.

Keep in mind that any of these methods will not show you Ubuntu in it full speed. When Ubuntu is actually installed on your machine will run faster.

Here is a quick little tip for if you operate a computer in a dual boot setup with Ubuntu and Vista.

do exactly this, because I've been programming Ruby and Ruby on Rails applications from Ubuntu, but the lack of Photoshop is killing me. So I did some research and eventually discovered andLinux (the future of the one-day), which lets you run Ubuntu Linux as a Windows service. So it is now solved all my problems when it comes to being able to do the design and programming at the same operating system (which I really need to do is buy a Mac, but who has so much money?).

, so I booted into Linux in about 3 months. It's no big deal, because it's nice to know that there is a partition exists, if we need it. But the problem is that I recently started running a little low on hard disk. I found it kind of strange because I was only about 2,000 songs on my computer, and now very few films.

But I have the 40GB Linux partition just sitting there.

So I went to delete the partition and recover some space. What is important though is that you make sure to replace the Linux bootloader that is installed when you install Ubuntu, or you will lose the ability to boot into Vista after you delete Ubuntu. So let's start with replacing the bootloader first in order to avoid any problems. The process is pretty simple:

1 First you need to download Super Grub Disk and burn ISO image CD.
2nd Next, pop the disc and restart your computer.
3.Super Grub Disk screens are kind of cryptic in the sense that a lot of choices look like gibberish, but it's important you want to delete Linux, so that only Vista:
WIN => MBR &! Win! :(((((((((((((((((
4th This option resets the Vista bootloader to the Master Boot Record, forcing your computer to automatically boot the next time Vista starts up.
5th Now, restart your computer, click "Start", right click "Computer" and select "Manage"
6th On the left side (in the menu tree), click on "Disk Management"
7th Find your old Linux partition, right-click it and select "Delete Volume"
8th After deleting, right click your existing Windows partition, and click "Extend Volume"

Now you should have recovered from the premises of the old Ubuntu installation. If you have a swap partition for Linux, you can delete that as well.

Now just remember that it is only after back up everything on your Linux install!

EXT2 (second extended) file system is an advanced file system for Linux kernel. This is the replacement of external file system. It is possible to resize the ext2 file system, while mounted, and the system it uses. It is possible to use ext2online utility. The process of resizing the file system while applications are open files and write data to a file system is fine. However, you should always have complete and valid backup of critical data before installing or online file system mounted. In case something goes wrong, you may encounter serious data loss situation, which requires the Linux data recovery to be fixed.

You can resize only mount Ext2 file system. To use ext2online utility, you must have online support for ext2 size (CONFIG_EXT2_RESIZE) be enabled on your Linux Kernel. You can enable this feature after applying the appropriate patch for the 2.x series kernel.

File system, which is specified by the device, or Mountpoint must be mounted immediately. By default, the mounted file system is increased to fill the device. If you specify an additional parameter size, and then use it instead of a certain size. If the optional modifier is not available, it is taken from Ext2 file system blocks.
