Linux Tutorial

For the uninitiated the GNOME Shell Extensions is an official project of the Gnome team which allow you to add new features to Gnome Shell.

We could for example add the permanent dock on the right side of the desktop, add the POWER button on a permanent basis, add new themes in a simple and fast and much more.

As mentioned in previous articles the GNOME Shell Extensions are already present in the official repositories for Ubuntu and Fedora 15 (today) are not yet present.

For this reason we decided to start in GNOME PPP LffL Shell Extensions with which we can install our extensions with ease and keep up to date.

Here’s how to install GNOME from Gnome Shell Extensions PPAsu Ubuntu.

To install GNOME on Ubuntu Shell Extensions 11:10 to 11:04 just start the terminal and type:

sudo apt-add-repository ppa ferramroberto/gnome3
sudo apt-get update
sudo apt-get install gnome-shell-extensions-common

At this point we can install our extensions, we will find in the Ubuntu Software Center or by typing in a terminal:

1. gnome shell extensions-alternate-tab: Use Alt + Tab classic based on the windows instead of applications in GNOME Shell.

To install it just type in terminal:

sudo apt-get install gnome-shell-extensions-alternate-tab

2. gnome shell extensions-status-menu-options: add the button turns off permanently without any time by pressing Alt to make it appear.

To install it just type in terminal:

sudo apt-get install gnome-shell-extensions-status-options-menu

3. gnome shell extensions-auto-move-windows: Allows you to manage the work areas more easily, the assignment of a working space for each application, as soon as you start a dialog.

To install it just type in terminal:

sudo apt-get install gnome-shell-extensions-windows-auto-move

4. gnome shell extensions-dock: It does nothing but add a permanent dock on the right side of the desktop. This is the same dock that appears when you access ACTIVITY ‘

To install it just type in terminal:

sudo apt-get install gnome-shell-extensions-dock

5. gnome shell extensions-Gajim: Adds integration with Gnome on our Shell Gajim

To install it just type in terminal:

sudo apt-get install gnome-shell-extensions-Gajim

6. gnome-user-shell-extensions-theme: to choose new themes in a simple and fast!

To install it just type in terminal:

sudo apt-get install gnome-user-shell-extensions-theme

7. gnome-shell-extensions-windows-navigator: allows the selection with the keyboard in windows in the areas of work in overlay mode

To install it just type in terminal:

sudo apt-get install gnome-shell-extensions-windows-navigator

8. gnome-shell-extensions-xrandr-indicator: it replaces the indicator based on GTK + gnome-settings-daemon with a native Allows the user to rotate the monitor of the laptop

To install it just type in terminal:

sudo apt-get install gnome-shell-extensions-xrandr-indicator

Once installed you must reboot to activate the extension Gnome Shell to do this press ALT + F2 and give the command r

Now we have started our extension on our Gnome 3

Ubuntu is too difficult to tackle and change? Get help from Ailurus to customize and improve it.

One of the things that baffle novice users find Linux is no longer certain functions that were easily available in the Windows world. The first operations were resolved with a few clicks now pass through “mysterious” commands like sudo, adding the repository or the use of the terminal that both frightens those who are not accustomed to using it.

To make life easier for those people, and maybe not just them, there are programs to help as Ubuntu-Tweak or Ailurus, we’re going to discuss in this article. This software allows us to implement several changes to the operating system configuration, install programs and more easily.

Installation

You can download the deb files with the latest version of the program from this address. Ailurus is also compatible with Fedora than Ubuntu and Mint.

If you want to install terminal enter these commands.

sudo apt-add-repository ppa Ailurus

sudo apt-get update

sudo apt-get install Ailurus

Operation

Once installed, the program is located in Applications – System Tools – Ailurus.

When you first start the program you see a warning about the impossibility to install proprietary software and the installation of certain codecs to avoid violating the law, check the box, I agree. Do not ask me again so it will not ask again. Then click Yes

The operation of the program is extremely simple, and, moreover, the interface is translated into Italian.

It begins with the Information screen where you can read the features of your hardware and operating system installed.

It continues with a series of small improvements to the visual appearance of the desktop, boot screens, special configurations of Firefox, setting some restrictions on user functions and much more. The voices are many and very clear: to consult you first to explain that one by one.

We will now install, automatically and without demands on the user, a series of programs and Firefox extensions.

Also good cleaning function of the system that allows the elimination of unnecessary programs and packages.

You do not have to do is confirm the removal when required.

Report (and correct) errors of the operating system and recommend improvements.

Of Ailurus are released very often new releases to add new tricks and improvements, once installed will be updated automatically as it does for other programs.

All ‘knowledge of all use LXDE for about a month. A few weeks ago, as some of you know, I started to wander between the various desktop environments under development with a certain arrogance and complacency, as if I myself, son of the CEO of HP.

The truth is that I have a PC, a maximum of two (stretching as far as possible the definition of “personal computers”).

What I usually do when you get that time of year when the new GNU-push me to try any project can only remotely be called alpha is targeting a mini-de-no-big-claims to be installed on PC’s to use in case of emergency. This little trick has been very helpful whenever I have found a stone’s throw from the voluntary and premeditated destruction of the laptop in question.

This year I threw a dead weight on LXDE! Here’s how it appears on my screen.

I felt the strong urge to write a post about it, maybe because I have a moral duty to tell you about considering his eagerness to me * _ *, perhaps simply because I want to.

I’ll spare you the usual introduction of this time he was born, what it is, what range of use is located. Suffice it to say that uses Openbox as window manager and is a stay buttons with ED!

I speak instead of LXpanel and how to beautify your desktop with a splash of compositing.

LXpanel the panel is lighter and more functional at the same time you can find in the linux-sphere. I take full responsibility for what they say. Its use, much like GNOME 2, is based on the use of applets, or additional basic functionality that you can import as and when you want.

The panel is highly configurable and above all in the geometry can be any size you want and through the inclusion of margins can be placed almost anywhere. The beginning I had put off the screen o_0

I really like the “application launch bar” that allows you to add, without much thought of, all we need fast connections: the file manager to open the latest installment of your favorite TV series, the browser for download torrent the next episode, the terminal to kill vlc when it realizes that your drivers for the NVIDIA is a bit ‘too much development, even the file manager to remove the old saw that 250 episodes are few gigs!

The notification area is simple and spartan, the director told me that in any case, it is able to notify. I can assure you at the time because I did not contact anyone! 0w0 (I do not believe it!).

Also the taskbar has a why. You can configure many aspects of its behavior through a dozen of checkboxes where you have put on, aware of the consequences, good ol ‘checkmark. Warning! I say, always the director, that every wrong answer on the checkbox will be imposed a penalty of one quarter to vote!

What else can I tell you. Yes, compositing. If by chance you want to enjoy some shading and maybe some fading on your desktop you can use the lightweight xcompmgr. Surely you can find it in your package manager, is present in the repositories of Ubuntu and Fedora.

Once installed within the session to start it you just press ALT + F2 and give the command xcompmgr-c, but if you want to add one of the LXDE startup applications do this:

• open a terminal (the one in the history of VLC, the first few paragraphs)
• go with administrator rights with your file manager to the location /etc/xdg/lxsession/LXDE, for example with nautilus: nautilus/etc/xdg/lxsession/LXDE
• open the file *autostart
• paste the following line at the end @ xcompmgr-c (for some work with the end of the line, ie a space and a “and” commercial after the c, not me!)
• saved
• restart the session

Besides the “c” which offers a compositing “base” you can add other parameters, I refer you to a specific page on the potential for xcompmgr.

Well, I’ve bored you enough. Do you like LXDE? Prefer XFCE? Would rather watch the water drain? Let me know!

This guide is intended as a reference for all those who, like me, once installed Fedora 15, were left bewildered.

You too have tried to crush the right mouse button a little ‘anywhere, right? You do not open any drop down menu Smile. Matter of habit, then see some tricks together.

Enable Desktop Icons

$ su
# yum install gnome-tweak-tool

To reach the menu: Tasks -> Applications -> Accessories

To display the icons go to File Manager and set the box to ON. When I set this setting gave me error due to the lack of a file. If you have not been corrected you can fix by running a terminal (as user):

$ cd ~ /.Config /
$ mkdir autostart

Enable buttons minimize / maximize the window (so to speak, the – and the square next to the X in the upper right of each window)

See Enable icons on the Desktop to install & position in the menu.
To bring up the two frets just go on Shell and the box set to your liking Arrangement of buttons on the titlebar.

Turn off the computer

To turn off your computer you should NOT end the session and then later turn it off. No. Just go to the upper right where there is its name, click on it. You will see a menu. Well, now you just hold down the ALT key and instead of heading should appear on the Pause Off.

Commitment to minimize all

The new philosophy seems to be the gnome against the use of this option. The idea would be to use a lot of work space and move with CTRL + ALT + CTRL + ALT + up and down. For those who just can not live without:

Click on your name at the top right -> System Settings -> Keyboard -> Shortcuts -> Navigation -> Hide all windows normal
Enable the box and put for example CTRL + M (just press them). Now, whenever you want to restore your Desktop just type CTRL and F simultaneously.

Configure your printer.

A few days ago I tried to configure my network printer by Samsung the only tools made available (accessible from System Settings -> Printers). Unfortunately I could not finish anything. If you are unable to configure your printer to the Christian way and you need a panel of more advanced configurations, you can directly use CUPS. To enter simply go to http://localhost:631/ with a browser. Here there are all the advanced settings that will definitely be for you.

Del-ellare files

If you try to delete a file with the classic delete key does not work … The new combination is CTRL + DEL to do so.

The bluetooth does not work

It occurred to me that the bluetooth is not working well. Reading on the internet seems to be a common problem. Here’s how to fix a terminal …

# enable systemctl bluetooth.service
# systemctl start bluetooth.service

Here are the steps for installing Fedora 15 Lovelock on a PC with a single harddrive and with Microsoft Windows preinstalled.

Many of the computers on the market currently have the new Windows operating systems preinstalled and preconfigured, this guide, aimed at newcomers Fedora Linux, also takes account of how to install Fedora on a partition adjacent to the Windows system, so we see the steps to be .

Getting Started

1 – Make sure the number of partitions which divided the harddrive of your computer.
Most PCs (Windows 7) In fact, have at least three partitions:

/boot Partition Boot
/system Partition System
/recover Partition containing the image file recovery

We are already 3 primary partitions that take up the entire harddrive, we can only create another for Linux. At this point we can burn the recovery DVD and then downloading the third partition (/recover) to free up space or keep the 3 partitions resizing the Windows system.
In both cases the operation is very delicate, if you have any questions please contact us in the forum.

2 – Backup your personal data (documents, emails, photos, …)

3 – Disk Defragmenter from Windows
It allows the “reorganization” of the operating system files to fill properly the space of the partition. I suggest you follow these directions if you’ve ever done.

4 – Reduction of the Windows system partition
This is the most delicate of the entire guide that can be done with both Windows and Linux in the first case I refer to the official documentation, in the second case recommend using Gparted Gnome Partition Editor.

Gparted is installed on Fedora live use (obviously need an active internet connection) between the applications and select Terminal type

      su ↩ send
      yum install -y gparted  ↩ send
      gparted ↩ send

Official Documentation → Resizing a partition

5 – Download the Fedora 15 Live image from the official page, you can download via torrent or direct download or via your PC based architecture (32bit or 64bit).

6 – Verica of the live image before burning to CD: Instructions : fedoraproject.org/it/verify

7 – Burn to CD write speed low

8 – Configure your bios to boot from a CD drive, depends on the bios used so you should read the instructions on their own or if it is complicated, open a discussion forum.

Installing Fedora

The images are virtualized installation of Fedora 15; Gnome-shell because it does not appear automatically disabled. In fact, the live system loaded from disk automatically detects the video resources of the PC, if not sufficient-shell does not start Gnome Gnome as showing in the pictures below.

9 – Once you have burned the image, insert the disk into the drive and restart your PC

10 – The following pictures show how to start the installer with Gnome-shell and without:

Start the configuration and the subsequent installation of hardisk space previously freed.

11 – Choose your language

12 – Choosing the type of device (in our case based)

13 – Host name and time zone

14 – Choosing the root password (minimum 6 alphanumeric characters and non-case sensitive)

15 – Choice of installation method. In our case, choose Use Free Space (Use space) with which the installer identifies the unallocated space freed in the preliminary phase as the partition to use.

Remember to select the bottom left of the item and modify partitioning layout Review (review and change the setting of the partition) to control what will Anaconda disk.

16 – Following a series of images that show how to use the free partition provided to Anaconda: by default in the system partitions are organized as logical volumes (LVM)

[---------------------------PV--------------------- --------------]
| _/Boot_|-|_____________________VG_______________________________|
| (_lv Swap_ )(______________-lv-root____________________) |

The partition then becomes a PV (physical volume or physical volume) recognized it as a harddrive (though physically it is not), within the PV, 500 MB is allocated to the / boot partition while the remainder is identified as VG (volume group or logical volume group), the VG contains partitions / swap and / (root) recognized as LV (Logical Volume or logical volumes).

For further information about what the ‘official documentation or refer to the LVM future guides.

17 – Everything is ready for the actual installation. From now on you can not go back.

18 – Installing the bootloader. Fedora system usually recognizes the pre-installed Windows (Other) and lists it among the systems to be launched

Other system in selecting and pressing it on Edit to change the name and maybe we can set it as default boot system while leaving other items

19 – Installation.
The duration of writing data to disk depends on the power of your PC, so be patient.

At the end of the installation, restart your PC by removing the hard drive from Fedora.

20 – User Configuration
Immediately after loading the bios, the screen of GRUB (bootloader), and if you do not touch any key, Windows will start directly in accordance with our settings during the installation phase, on the contrary, by pressing the up-arrow you can choose to start Fedora.

The settings are pretty simple to do:

• - License Information
• - Creation of user / password
• - Automatic synchronization time / date or manual setting
• - Send your hardware profile or not

Without this there is nothing left to login with the user you just created and enjoy Fedora 15 Lovelock.
