Ubuntu Post installation Introductionz

So, you are reading this because probably you have installed ubuntu right and now you need to know about the system and how it works and how can you optimize the system for better efficiency, for better look and how can you customize it like you can do it in windows! Well, look no further, you can get all those tips right here! Here is a “Beginners guide to ubuntu tips and optimization”.

So, lets learn a few things about ubuntu, that you might want to know as a first time user.

First boot:

When you for the first time boot the ubuntu system, what you see is a boot flash screen which is called a USplash and it covers up what is going on in the background when linux is booting. This screen is introduced so that the users who arent interested in what actually happens in the background, dont really see it.

First Login Screen:

On the right side of the login screen, you will notice the name of the computer, the date and the current time. On the left side there are some very useful options, like reboot, shutdown, suspend, hibernate, change session etc. Ok, it’s time for you to type in your username and password (hit enter after each one). Immediately after you’ve typed your username and password, you’ll notice a splash screen that shows what programs are loading and in a few seconds the splash screen disappears and the Ubuntu desktop appears. That’s the Ubuntu desktop!

Gnome Desktop:

The desktop environment that ubuntu uses is the GNome desktop! If you have a DHCP based network connection (automatic IP address) then you are connected to the Internet as Ubuntu configures DHCP connections automatically and you will notice a notification message in the right-upper part of the screen that says “Software updates available”. Click on the new orange icon (from where the notification message appeared) and a window will appear on the left side of the screen. This window will start to search for updates. Click the Install Updates button, when the search is complete, to install the available updates on your system. Ohh, what’s this? It asks for a password, because this is an administrative task and it’s safer this way; just type your password and hit enter. This program is called Update Manager and you can always find it under System -> Administration menu, but it will always appear when there are new updates. Also, you will notice another notification message that will ask if you want to install proprietary drivers for your graphics card. Just click the Enable option and it will start to download and install the necessary drivers.

Panels and Applets:

et’s learn a few things about the desktop. First things first, you should know that this desktop is called GNOME; as you can see, it’s a little different than Windows, as it has two Panels: one at the bottom and one at the top. But what’s cool about this desktop is that you can always configure it however you want, but we’ll talk about this a little bit later. Both panels have the same options and configurations.

The bottom panel has the Show Desktop button on the left side; in the middle you will see all the current opened windows and on the right you’ll see a trash icon and the Workspace Switcher. Now this is something you didn’t have in Windows (at least not as default), as the Workspace Switcher allows you to have multiple desktops. How does it work? Very simple: on the actual desktop, you have a window (or more) and if you click on the second square (default there are only two desktops, but you can set up to 36 desktops) the window(s) will disappear. Why? Because they are on the first desktop (you can even see them in the first square), and if you click the first square the window(s) will appear again. On the second (empty) desktop you can have other window(s). Come on, try it yourself to see how it works!

The upper panel is a little more complex. It contains on the left side the Main Menu from where you can access all the applications, different system locations (home folder, network places etc) and the system configuration tools. Right after the Main Menu you will see some software icons; these are shortcuts for different applications installed on your computer and you can add there as many as you want with a simple right click on the panel; then click on “Add to Panel” option and when the Add to Panel window appears hit the “Application Launcher” button on the left side and select your favorite applications from the list. On the right side of the upper panel you will see two icons (the network monitor and the sound volume), the date, the clock and a shutdown button from where you can reboot, hibernate, suspend, log out, switch user, lock screen or shutdown the computer.

I think this is enough for today, with respect to the customization of the ubuntu desktop and the next part of this tutorial will include topics like how to install new software on ubuntu linux as well as how to make your desktop cool and funky!

The best thing and the worst thing about moving to a brand new operating system is all of the new applications that are immediately available to you. With Ubuntu, an open-source GNU/Linux based operating system, this is compounded even more by the astounding number of options along with the close-to automated package management system and strong community support.

Therefore, it’s helpful to have a basic guide to guide new and returning users through the varied software options by highlighted specific popular packages and providing installation directions, along with information about where users can look for more options and support. By showing the new Ubuntu user the best of the software repository from the start, we can ensure retention and thereby further undercut the market share of the 8,000 pound gorillas in the OS market.

Seeing all of the software available for Ubuntu through the official repositories is an easy and enjoyable experience. In fact, you don’t even need to open an internet browser. You can see the repositories (or repo’s) in two different ways:

1. Click on the Add/Remove Programs option in the Applications menu. This will most of the more popular items, along with each package’s estimated popularity. The option to install is provided right through the dialog screen.

2. Use the Synaptic Package Manager, which is available through selecting System–>Administration–>Synaptic Package Manager. A search function is included, making this process even easier. Also, you can choose to update all of your current packages through the click of the button. More often than not, no restart or reboot is required.

Without further ado, here are some common applications for Ubuntu, and directions on how to install them.

BitTorrent

qBitTorrent is an application used to connect to the BitTorrent file sharing network, which acts as an uncentralized way to distribute and download large files without much hassle. Many sites on the internet provide these torrent files, and it is the responsibility of the user to make sure they are not violating the copyright laws of their respective nation by using them.

qBitTorrent is not available in the official repositories, so you’ll have to use the Terminal to install it. You can access the Terminal through Applications -> Accessories -> Terminal. As soon as it opens, enter the following commands (a root password may be required).

gksudo gedit /etc/apt/sources.lst

Copy the following lines to the end of the file:

deb http://hydr0g3n.free.fr/qbittorrent/feisty/ ./

deb-src http://hydr0g3n.free.fr/qbittorrent/feisty/ ./

Close the window, and copy and paste the following command:

sudo apt-get update && sudo apt-get install qbittorrent

Evolution

Check your e-mail in style with this client. Evolution comes pre-installed with Ubuntu, and you can open it from the Applications menu. This program is ideal for calendaring, keeping track of contacts, and checking e-mail. If it isn’t installed for some reason, you can install it with the Synaptic Package Manager.

Pan

Pan is a way to connect to UseNet. It’s one of the few for Ubuntu that has a graphical display.

Type this in to install it:

sudo apt-get install pan

Pan rivals the XNews program for Windows, and it’s completely open-source.

Firefox

Firefox is a really quick web browser developed by Mozilla. Yep, it definitely knocks the socks off of Internet Explorer, and it’s way more compatible with most websites than Safari. Based on the latest statistics, more people than ever before are moving over to Firefox from other browsers, and almost everything on the internet is compatible with it. Though it comes pre-installed with Ubuntu, I definitely think it’s worth a mention. If it’s not preinstalled, type this in the command line:

sudo apt-get install firefox

Pidgin

Multi-protocol Instant Messaging, baby! Includes support for AIM, Yahoo!, GMail, and MSN. I know, I know, it’s amazing. And trust me, it is EASY to install!

Here’s the directions: Insert this stuff into your command line.

wget http://vicox.net/ubuntu/pidgin_2.0.0beta7devel.vicox-1_i386.deb

sudo dpkg -i pidgin_2.0.0beta7devel.vicox-1_i386.deb

I hope this was a useful start. For more application ideas, you can try the official documentation or the forums. Good luck, and enjoy your new experience with Ubuntu!

Text and images (scans of census records) are crisper and sharper and the LCD monitor is easier on your eyes. Monitor’s size: Traditional monitors are similar to a TV because both of them have the CRT (Cathode Ray Tube). That is the reason for its bigger size. It therefore occupies more space at the desk. It is also heavy.

However, LCD monitors have thin flat screen. Therefore occupies very less space and is lighter than the CRT monitor. LCD monitors can be fixed even on wall. Display Size: Even though the display size of a CRT monitor is calculated diagonally, the actual display size is smaller. For instance a 17″ CRT monitor will actually have a display size of only 16″ However, the display size of 17″ LCD monitor will have 17″ display size. Resolution: CRT monitors can show different resolutions. The resolution can be changed as required. LCD Monitors will have Native Resolution and therefore has a fixed resolution. The best resolution will be the native resolution for that LCD monitor. Viewing Direction: A CRT screen can be viewed from all directions. And from different distance. But LCD monitors cannot be viewed from all directions. LCD monitors can only be viewed straight. Therefore its viewing direction is limited. If viewed from other directions the colors will change and sometimes the vision will be unclear if not viewed straight. But in recent years the new LCD monitors have improved on this defect. Radiation Emission: The radiation emission in CRT monitors are higher. This will not be visible normally but it will affect eyesight and may cause head ache. Long term use of these monitors may even affect the eyes adversely. LCD monitors do not have this type of Radiation emission. Therefore LCD monitors are good for the eyes. Price: CRT monitors are priced very cheap. However they consume more power. LCD monitors are priced higher, but they consume less electricity. Though the electricity consumption is not very significant for personal use, it is very cost efficient in big organizations with many computers.

Monitor

Text and images (scans of census records) are crisper and sharper and the LCD monitor is easier on your eyes. Dot pitch: This is the space between dots and is measured in fractions of a millimeter, e.g., .25mm. The smaller the number the better because the dots are tighter. Many manufacturers don%u2019t even list the dot pitch anymore and you probably won%u2019t be able to tell the difference between a .22 and .27 pitch anyway. So, if you like the monitor then don%u2019t worry about the dot pitch. Passive-matrix vs. active-matrix: Do not buy a passive-matrix monitor. I seriously doubt you%u2019ll even see one for sale, but%u2026just in case. Having said that, there are some new passive-matrix technologies that are worth buying. If the monitor isn’t TFT (a type of active-matrix), look for CSTN or DSTN (the latest passive technologies). Brightness: How bright is the picture, expressed as cd/m (I have no idea what the units mean). Look for a brightness level of 200 cd/m or greater. Again, if the monitor specs don%u2019t list this value (not all do) be sure you can get your money back. If the lighting in your office (kitchen table) is subdued the brightness factor won%u2019t be as important as if you have a lot of sunlight streaming in. Don%u2019t pay extra for extra brightness unless you%u2019re worried about bright sunlight. Overall, the contrast ratio will have a bigger impact on picture quality. Monitor’s size: Traditional monitors are similar to a TV because both of them have the CRT (Cathode Ray Tube). That is the reason for its bigger size. It therefore occupies more space at the desk. It is also heavy. However, LCD monitors have thin flat screen. Therefore occupies very less space and is lighter than the CRT monitor. LCD monitors can be fixed even on wall.

Resolution: CRT monitors can show different resolutions. The resolution can be changed as required. LCD Monitors will have Native Resolution and therefore has a fixed resolution. The best resolution will be the native resolution for that LCD monitor.

CRT

Speaking of easy on your eyes, there isn’t any glare, and the flat screen means no distortion. By the way, even those expensive old-fashioned flat screen CRT monitors have some distortion.

Ever wondered “whats inside”??? Here U can see it. My old monitor… Before bringing it to a junk-jard. I take out some parts i still can use. The explanation of the transistors was not really correct. The transistor for the power-supply is on the other side of the circuit board.

I have a lot of friends that have LCD monitors (I prefer CRT still) and most of them are complaining about stuck pixels and how they can repair a LCD monitor that has this type of problem. I will show you 3 simple ways that you can use to get rid of this problem without having to go to someone else and maybe pay that respective person. Stuck pixels usually appear because the liquid inside the LCD monitor is not spread properly, and so 1 or more pixels may remain stuck with one color or just stay black, it depends. But now lets get down to the explaining part. 1. I will start with the software method, since this is the one that most people prefer and it is also the easiest way to repair LCD monitor that has a stuck pixel. I have 2 software programs that can do this and they are free, just search on the internet and you will find plenty of them. 2. Trying to repair the problem using pressure. What you have to do is, start by turning off your LCD monitor and then find something like a pen that has a small rounded end but it is still thin, you must use this since if it is too sharp you may scratch your LCD. Then get a small damp cloth to protect your LCD monitor from scratching, fold the cloth in 2 and place it exactly over the stuck pixel and start adding a small amount of pressure on it with the pen, DO NOT press hard or you will risk to further damage your LCD monitor and also DO NOT add pressure anywhere else besides that pixel. Now, while adding pressure on it, turn on your LCD monitor, then remove the pen and the stuck pixel should be gone. 3. And the third method is fixing the stuck pixel by tapping. Start by putting a black background on your display, and I mean black and make sure you leave your lcd monitor turned on. Then get a pen or something thin but with a rounded end and start to gently tap the stuck pixel until it disappears,you should have a steady hand for this so you wont tap other pixels. You know that you’ve added enough pressure on your taps if the screen glows white around the pixel. It should fix it after a few taps. I hope this article helped you in some way, and you may repair your LCD monitor’s stuck pixels. As a final note I want to add that there is no guarantee that these methods will work, you try them at your own risk.
