Ubuntu 12.04 connects but we can not browse: here is how to solve the problem

Ubuntu 12.04 connects but can not browse here is how to solve the problem
 
The new Ubuntu 12.04 brought plenty of new features: from the improvements of Unity in the new HUD, Update many packages, among them are also Network Manager updated to new version 0.9.4 that brings many improvements, available from this page.

Some users have reported that once were able to connect, but can not navigate: this problem is quite common especially for users who use the Internet via mobile devices such as keys, cell phones, or using Ubuntu in Virtualbox.

The problem is due to DNS, which are not properly recognized and managed by Network Manager, but here's how to solve this problem.

First you need disconnect from the internet, this is done, we start the terminal and type:

For Ubuntu
sudo gedit /etc/resolv.conf
For Kubuntu, Xubuntu, Lubuntu
sudo nano /etc/resolv.conf
And insert as shown below:
# Generated by NetworkManager
nameserver 8.8.8.8
nameserver 8.8.4.4
Then save (if we use nano we have to press CTRL+X then S)
and try to connect through our browser, and if we need to navigate to lock the configuration and to do that, we finish the connection and terminal type:
sudo chattr +i /etc/resolv.conf
Now we locked configuration and Network Manager can not modify it and then we can connect without problems.

To unlock the configuration, always terminal type:
sudo chattr -i /etc/resolv.conf
In case of problems, please do not hesitate to report commenting on this article.

Unity 5.12.0 released: more speed and many bug fixes! [Installation on Ubuntu 12.04]


Include a discussion and the other with my dear friend, I learn that, indeed by very few hours, Canonical has released an update related to Unity so that the salt Version 5.12.0. This is not a release but particularly rich in novelties, with this update, developers have introduced more than 65 fixes to as many bugs, and have significantly improved the speed and stability of the Ubuntu desktop.

Among the many bug fixes, we mark that finally there are more problems with the album covers in Music Lens..

To install Unity 5.12.0 on Ubuntu 12.04 Precise Pangolin all you need to enable proposed repository (Go to Settings -> Software Update -> Settings -> Updates) And then check for new packages and install them. If you are interested in the full changelog for Unity 5.12.0, you will find it in this page.

The new boot sound of Ubuntu 12.04 Precise Pangolin? Does not exist!


What I found incredible, but I was also confirmed by some members of the Ubuntu team. After installing Ubuntu 12.04, I switched the speakers to enjoy the new sound of default introduced in Precise Pangolin: nothing. Then I thought it was a stupid question, so I went to Settings -> Applications boot to enable sound and found nothing! Never mind, I decide to manually use the command to enable it:
/usr/bin/canberra-gtk-play --id="desktop-login" --description="GNOME Login"
But ..... Now run this command from a terminal. Notice anything strange? Well yes, Ubuntu is the old sound, not the new! So I have not given us peace and tried another directory, another file:
/usr/share/sounds/ubuntu/stereo/desktop-login.ogg
And nothing is the same identical African sounds we already know! What happened, then, the much-loved, new sound from Ubuntu which was to begin with Precise Pangolin? Was not included! Unfortunately you do not know the reasons for this sudden choice not to include it, so that even some of my friends are Canonical developers was a bit 'too stunned.

The mystery deepens, but as soon as I can find out more, I will inform you immediately!

Installing Ubuntu 12.04 crashes because of the Broadcom card? Here's how to solve

 
I am sorry to say, but unfortunately the problems of crashes of Ubuntu reserved for Unfortunate owners of Broadcom NICs has been running in Ubuntu 12.04 Alpha 1. What happens? Splashscreen system (meaning the screen that says Ubuntu with the five circles that simulate a loading bar) Suddenly disappears, crashes your computer completely and forcing you to restart it using the reset (Or, in the case of Notebook, Off and on).

Before you continue reading, however, do a little experiment: press the F2 key when the splash screen appears and set all the writing that appear on screen. If the boot is stops immediately after the appearance of this notice
b43-phy0 ERROR: firmware file “b43/ucode5.fw” not found
b43-phy0 ERROR: firmware file “b43-open/ucode5.fw” not found
b43-phy0 ERROR: You must go to http://wireless.kernel.org and read all the instructions on this website.
or something very similar ... so yes, this is the post for you.

I know what you're asking yourself: one, the solution exists… you, I also own a Broadcom and I had the honor of hitting this bug and ... no, no need to remove the network card it to abandon its use.

There's something cute typical Unix-like systems is called blacklist of modules: It is a real blacklist which contains the modules that the system will not dare absolutely to load even with a gun pointed at the processor. By default, this list is empty, but can be filled gradually as needed.

The reason why the system plant before the installation is just the form on Broadcom network adapters, Such form b43, Which for some reason refuses to work on Precise. Well, if a plant has a dead branch not the plant breaks down, but that branch is pruned: We, through the directives boot, put temporary blacklist the b43 module included in the system and then install a functioning. Now we turn to the practice (it is a bit 'clunky, but I assure you that it is efficient. I tested it in person ...). I tell you beforehand that you will need an internet connection independent of the offending network card, since there are files to download.

Insert your device into your computer containing the installation ISO of Ubuntu (Whether CD, DVD, USB stick or whatever), wait for appearance of this screen

and Immediately press a button. Choose the language of the installer and press enter. You will see something similar to this:

at this point position yourself to "Try Ubuntu without installing" or "Install Ubuntu" (Is irrelevant) but DO NOT PRESS ENTER: instead the press F6, Immediately followed by the ESC key: You should be able to write in a textbox. Now go (in the textbox) more to the right that can, leave intact the existing text and write, Appended to it (and being careful that after the two dashes there is a space), the string

b43.blacklist=yes
after that press Sending.

system installation will start and will not hang over! Clearly If you do not have a network device Alternatively you will be forced to install without the help of the network.. but it is not a problem, once installed the system and reconfigure the wireless card you will have the opportunity to update and download all the packages you want! But there's more.

Yes, it is true, the OS will install without problems, but ... if you try to start it from GRUB will end up with a crashes identical to the previous. What do we do? Well, blacklist the b43 directly from a GRUB boot.

if GRUB does not appear to you and the system would default Ubuntu, make sure that the loader to appear by pressing and holding down the shift key while starting the computer, immediately after the BIOS POST (Basically disappear since all those written in ancient Aramaic).

We select from GRUB, the option related to Ubuntu 12.04, this time FREE PRESS ENTER: Press the button instead and. You will see the text editor of the boot entry: we place next to "vt.handoff=7" using right and left arrow keys, Leave a space, and write once again

b43.blacklist=yes
(get the symbol "=" pressing the button marked by the accented "i" on the keyboard ... eh, I know, damn American keyboard!) after that press F10.

Our system ... boot! But Broadcom will continue our course does not work. Come on, you're almost done! And ... restart the computer! From this moment onwards your Broadcom will be up and running!

NB: someone will tell me that the drivers are also present in the Ubuntu repositories, and that there are special kernel headers ... well, with my card even as they refused to work, let that be known

Good job!

Network problems for Galaxy Nexus and Android 4.0.4: no SMS or call ... possible solutions!


Google has confirmed the presence of a bug in the new Android 4.0.4 update for Samsung Galaxy Nexus: when the smartphone enters deep sleep mode, it loses the 'attachment to the telephone network, Making it impossible for the 'use of the telephone during normal use (no phone calls or SMS).

Some users have immediately noticed the presence of this error only in version 4.0.4: When you have two solutions ... certainly not optimal for the 'use of the Galaxy Nexus.
  1. Disable deep sleep mode
  2. Increase processor frequency to a value greater than 200 MHz
In both cases, the losers is the battery ... see what happens in the coming hours.

Facebook acquires Instagram for a billion dollars

In a move that few were able to predict, the social network Facebook has just acquired for a billion  dollars Instagram, The popular service that allowed edit and take pictures with different types of filters and effects from IOS and Android mobile devices.Mark Zuckerberg wanted filters to your photos hosted on your social network. And the shopping is over.

Although the service, where we share photos and images with different filters and effects with other users through our iPhone or Android phone, only about two years on the scene in recent months had begun to enjoy popularity and presence unusual being a whole reference implementation for IOS devices.

Instagram CEO ,Kevin Systrom, already been communicated in the company's official blogtheir impressions and reactions to the news, ensuring the future and the continued application and service despite the purchase by Facebook.

Instagram was beginning to reach a rate quite interesting in terms of updates, adding new filters, functionality and interface designs that meet the needs of users. The future of the application is now in the hands of the popular social network, which could integrate a deeper way services photo application. What's new Instagram now bring us?

Compilation Kernel 3.3.1 on Ubuntu x64 and derivatives.


This is a small guide for compilation and optimization of the kernel on Ubuntu 64-bit and derivatives. The optimization is limited only to select the type of processor inside the configuration files, additional optimizations can be performed within those files related to its hardware configuration.

The result of the work is a kernel compatible with all Intel belonging to the family Core2 , Corei3, i5, i7 etc.

This guide is not suitable for compiling the kernel on machines with AMD CPUs, soon I'll post one devoted to these processors.

The optimization provides better speed in the execution of tasks that absorb a lot of processor resources, eg encoding/decoding, compression/decompression, etc. files.

If we use our computer only to surf the net and write a few lines of text will notice big differences.

Before you start the real work just thank all those in network publishing every day their experiences improve our skills and enhance our culture. A special thanks goes to Sankaran Raman whose work I have drawn freely.

Start the "Terminal" and type at the prompt, just as there are in the order, the commands that will gradually during the reading. Each command is preceded by a brief explanation.

- Install libraries, compilers and everything needed. At each date command "Enter", type in your password and wait for the system do the rest.
sudo apt-get install fakeroot build-essential crash kexec-tools makedumpfile kernel-wedge libncurses5 binutils-dev libelf-dev libdw-dev libnewt-dev libncurses5-dev

sudo apt-get --no-install-recommends install asciidoc xmlto

sudo apt-get build-dep linux

- Create the folder containing the kernel source and patches within our home (at the end of all operations, it will also feature our beautiful kernel and compiled into individual packages).
mkdir ~/Kernel_3.3.1

cd ~/Kernel_3.3.1

- Download the kernel and patches.
wget -c http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.3.1.tar.bz2

Wait for the end of the download before giving the next command (for each individual command).
wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3.1-precise/0001-base-packaging.patch

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3.1-precise/0002-debian-changelog.patch

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3.1-precise/0003-default-configs.patch

- Unpacking kernel, creating symbolic link, access to the folder.
tar xjvf linux-3.3.1.tar.bz2

ln -s linux-3.3.1 linux

cd linux

- Patch Application to Kernel
patch -p1 < ../0001-base-packaging.patch

patch -p1 < ../0002-debian-changelog.patch

- Cleaning and updating the configuration file
fakeroot debian/rules clean

fakeroot debian/rules updateconfigs
- Edit the configuration file to adapt the kernel to our requirements: it is a fundamental step to be performed with extreme caution. Execution of the command, the terminal will display a series of questions, ONLY THE SECOND REQUEST YOU MUST  ANSWER AFFIRMATIVE.

fakeroot debian/rules editconfigs
  • Answer "No" to the first question, "Y" to the second. Now you came into the kernel configuration, proceed as follows (to select intend to move up and down with the cursor keys and then to enter):
  • 1 - Select "Processor type and features"
  • 2 - Select "Processor family (Generic-x86-64)"
  • 3 - Select "Core 2/newer Xeon
  • 4 - Scroll all the entries down to find "Preemption Model ..."
  • (This item determines how your cpu will "dedicate" to the management of various tasks/programs running on your system along with the item "Timer frequency ...". And 'possible to favor a faster system response times at the expense of actual execution of the various processes. I highly recommend leaving the "Desktop").
  • 5 - Scroll all the entries down to find "Timer frequency ..."
  • (Now if you can select a fixed 1000Hz, the laptop does not exceed the threshold 300Hz . On the web I found endless different explanations and tips on using this parameter, unless you use on your system of professional applications for managing Audio and video septate the value of 300Hz).
  • 6 - Go back to the previous menu, selecting "Exit" option on the bottom of the screen
  • 7 - Select "Networking support ..."
  • 8 - Select "Networking options ..."
  • 9 - Scroll all the entries down to find "The IPv6 protocol", pressed on your keyboard the letter "M"
  • (At compile time will create a kernel module for IPv6 that you can ban to prevent the use by the system in a definitive manner).
  • 10 - Return to the previous menu, selecting "Exit" option on the bottom of the screen
  • 11 - Return to the previous menu, selecting "Exit" option on the bottom of the screen
  • 12 - We leave the menu always selecting "Exit" option on the bottom of the screen
  • 13 - answer "Yes" to the question that will be placed at the exit, we will save your changes to the basic configuration.
  • Answer "No" to the next question present on your screen.

- Copy of generic and our configuration as the default setting in the build process

Linux Kernel 3.3.1 on Ubuntu and derivatives

Linux Kernel 3.3.1 su Ubuntu e derivate

A few days ago Linus Torvalds announced the release of new version 3.3.1 of the Linux Kernel.
The new release brings some fixes and adds new features, among which are better supported with Android (Merge). Improvements for the Btrfs file system: including the redesign of the balance of operations and the introduction Integrity Check. Also lands the new architecture Texas Instruments C6X (TI C6X), improvements and corrections for Open vSwitch and EFI boot. Thanks to the new interface Network Priority Control ,The system administrator can manage the priorities of the traffic network. this page find the changelog of the new Linux Kernel 3.3.1.

As with previous releases, the Ubuntu Kernel Team released packages dedicated to the new version of the Linux Kernel. So here how to install the new Linux Kernel 3.3.1 on Ubuntu and derivatives.

Linux Kernel 3.3.1 for Ubuntu (i386 / 32-bit)
cd
wget -O linux-headers-3.3.1_all.deb http://goo.gl/3rrEL
wget -O linux-headers-3.3.1-generic_i386.deb http://goo.gl/yr9lP
wget -O linux-image-generic_3.3.1_i386.deb http://goo.gl/NF7QP
sudo dpkg -i *.deb
sudo apt-get install -f
Linux Kernel 3.3.1 for Ubuntu (amd64 / 64-bit)
cd
wget -O linux-headers-3.3.1_all.deb http://goo.gl/3rrEL
wget -O linux-headers-generic_3.3.1_amd64.deb http://goo.gl/uIGJP
wget -O linux-image-3.3.1-generic_amd64.deb http://goo.gl/C9zBl
sudo dpkg -i *.deb
sudo apt-get install -f
After reboot, and we will have to restart the new Linux Kernel 3.3.1 installed in our distribution.

To test the reboot we type in terminal uname-r will show you the kernel version you're using if everything is correct:
~$ uname -r
3.3.1-030301-generic
To remove the new Linux Kernel 3.3.1 when installed by the end you just type:
sudo apt-get purge linux-image-3.3.1-030301-generic

And reboot.

In case of problems with nVidia graphics cards here is a solution to start the terminal and type:

cd /usr/src/linux-headers-3.3.1-030301-generic/arch/x86/include

sudo cp -v generated/asm/unistd* ./asm
And reinstall all packages as a guide.

Linux: 8 Golden tips to better use the terminal


Does not exist Linux distribution that does not require, at least a little, use the terminal. Having good practice and familiarity with the Linux shell is important and the purpose of this article, aimed at novice users maybe, is to provide some suggestions for learning how to better the Linux terminal.

Tab Completion

This is a fundamental trick: it is a great saving of time and is useful if, for example, you are not sure of the exact name of a file or a command. Suppose you have a file with a "very long" and we want to discard it: it may happen that we forget to write as well (such as the lack of \ that is used before each space character). Typing rm and by pressing the button Tab, The shell will automatically complete the filename and if we write the initial of the name of the file to be deleted is if we type anything (in this case we will provide the entire list of files in the folder where we are).

Pipes

The pipes (the character |) Are used to send the output of one command to another command. In the "philosophy" of UNIX, each program runs a small real function. For example, the command ls lists files in current directory and the command grep used to extract something. Combining the two commands, you can find for example the word: ls | grep word

Wild Cards

The asterisk (*) Is a wildcard character with which you can find everything: for example, with the command rm name1 * name2 we can delete all files that start with name1 and end with name2 (Careful not to put an asterisk after rm, which would result in deleting all the files in the folder)

Redirecting output

The character ">" redirects the output of a command to a file instead of another command, for example writing ls > testfile lists the items in that folder in the Print to File.

Command History

We are permitted to have access to the history of the commands used: you can use either the command historyor the arrow keys on the keyboard Highand Low.

 Symbols ~  .  ..

The character ~(Known as tilde) Is the directory homecurrent user: Instead of typing cd/home/username to go into the folder Home, You can type cd ~ (You can also add other links as soon as a /Desktop).

The character . represents the current directory.

The character .. represents the parent directory above the current directory. Also here you can add more links after the dots as /Desktop).

Run a program/command in the background

How to use the terminal while you are performing an operation that blocks its operations Input/Output? For example, if you type firefox to launch the browser Mozilla Firefox, Firefox  gets hold of your terminal until it is closed and will keep him busy. Writing near the Firefox symbol & you can run the command in the background and not lose control of the terminal.

Running conditions

In bash we decide to run two commands one after the other with the condition that the second run only after the first has been completed successfully for this is to write the two commands on same line separated by the symbols &&.

Were you already aware of all these suggestions?

  • Uninstall if installed, VirtualBox OSE.
Procedure:

Go System->Administration->Users and Groups (This path is valid for all those who have less than a version of Ubuntu 11.10, but if you have Ubuntu 11.10/12.04 you must first install the application Users and Groups terminal by typing the following command:

A new update of Virtualbox has been released. Somewhere is now available to download the version 4.1.12  which, with immense pleasure for users of Ubuntu, is finally compatible also for Precise Pangolin.

Installing using packages

All you have to do is choose from the list below and install it with your package a simple double-click:
Installing via PPA Repository

If you want to have VirtualBox up to datethe latest versions, being notified directly by the operator of the updates, then you can rely on PPA repository created by little.
sudo -v
echo "deb http://download.virtualbox.org/virtualbox/debian $(lsb_release -sc) contrib" | sudo tee -a /etc/apt/sources.list
wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -

Totally remove Unity from Ubuntu 12.04 Precise


This guide is for all those who, like me, appreciate Ubuntu but just can not digest the new license plate interface Canonical, Unity, For all those who are not content just to install another DE and select the login, but they also want eradicated from the system every single package, track and dependence of Unity. I do not want the passionate fans of Unity, have patience, are bastard (and picky). So:

We proceed to install Gnome Shell, his Account Manager (who will replace LightDM), good old Synaptic package manager and as a utility that will allow us to clean it up, in this case, each "residue" of Unity.

Open a terminal and type:
sudo apt-get install gdm gnome-shell synaptic deborphan
During installation you will be asked to set the default Login Manager, select "gdm" and continue. Reboot the system to log and choose "Gnome". We open the terminal and proceed to the removal of Unity in all its components, or open Synaptic and manually select the packages to remove:
sudo apt-get remove unity unity-2d unity-2d-common unity-2d-panel unity-2d-shell unity-2d-spread unity-asset-pool unity-common unity-lens-applications unity-lens-files unity-lens-music unity-lens-video unity-scope-musicstores unity-scope-video-remote unity-services indicator-messages indicator-status-provider-mc5 appmenu-qt appmenu-gtk appmenu-gtk3 lightdm unity-greeter overlay-scrollbar zeitgeist zeitgeist-core zeitgeist-datahub activity-log-manager-common activity-log-manager-control-center
Then type:
sudo apt-get autoremove
Now we proceed with the removal of all packages "orphans" who have remained in the Unity system with deborphan with:
sudo apt-get purge `deborphan`
We repeat the command several times to remove even the dependencies of dependencies, until we answer that there are more packages to be removed.

And finally, we eliminate even the small configuration file of Unity remained, by typing:
sudo dpkg --purge `dpkg -l | egrep "^rc" | cut -d' ' -f3`
We will then have a clean Ubuntu 12.04 and distilled, with only Gnome Shell.

Updating Flash Player 11.2 on Firefox 11 without problems!

Flash Player 11.2

Adobe has recently released the latest update (article here) of its Flash Player for Linux. However, myself and many other users have encountered many problems with this upgrade. In my personal case, for example, I could not fully display Flash content via Firefox ,Still others complain of minor faults, but it is annoying. How to fix?

As a good person who always chooses the safest and least vexed, I decided to open a post for help through the support of Firefox, you can see through this link. I was rightly advised to re-download the plugin from the official Adobe website and install it manually by copying the folder of the default plugins on Firefox, it did not work, From good to better. So I started trying to figure out why I had problems on Chrome and I started to look a bit 'that he used the plugin and found, to my great surprise, File a virtually identical ,Had it not been for a few more characters in its name. Moved a little 'rage for pretty dumb move by Adobe, I decided to put into practice the following procedure, which has worked well!

Open a terminal, let us go after installing Chrome in its folder:
cd /opt/google/chrome
Inside, find the file mentioned earlier: "libgcflashplayer.so", which we copy as "libflashplayer.so" so that Firefox will recognize it, if we let two more letters (probably indicate GoogleChrome, IMHO) :
sudo cp libgcflashplayer.so libflashplayer.so
So we turn our new copy of Firefox in the directory:
sudo mv libflashplayer.so /usr/lib/firefox-11
Now, we have to go with the terminal in the location where now is the plugin and copy it to the appropriate directory. To do this:
cd
cd /usr/lib/firefox-11
sudo cp libflashplayer.so /plugins
Of course we accept the request to overwrite the file and restart Firefox, now it's all right!

ALTERNATIVE We can download the file libflashplayer of Chrome and add it to our Firefox (whatever version) and is 32 or 64bit.
First, start Firefox and disabled the flash player plugin that you are using the section add.on -> Plugins and then type in terminal:
cd
sudo wget -O libflashplayer.so http://goo.gl/vHZiM
mkdir ~/.mozilla/plugins
cp libflashplayer.so ~/.mozilla/plugins
if you by mistake when you give mkdir ~/.mozilla/plugins do not worry it means that you already had the folder.
Start Firefox and have the new plugin of Chrome working perfectly in Firefox.
