Chakra GNU/Linux 2012.09

Anke Boersma has announced the release of Chakra GNU/Linux 2012.09, an updated build of the project's distribution featuring the new KDE 4.9.1 desktop: "The Chakra project team is proud to announce the second 'Claire' release. After the release of 2012.08 well over a thousand packages were updated, including a new sound stack, updated Poppler, OpenJPEG and OpenAl group, KDE 4.9.1, latest Calligra and LibreOffice. Because of all these changes, and to get back to having a release schedule that follows closely to the schedule KDE is using, 2012.09 is following the first 'Claire' ISO image rather quickly. It also gives us a chance to fix some issues found in that first release. Chakra is making the switch to PulseAudio as default with this release. See the complete release announcement for more details and a brief list of main features. Download (64-bit computer systems only): chakra-2012.09-Claire-x86_64.iso (1,589MB, MD5).

How To Install Nvidia Drivers Using Recovery Mode Under Ubuntu 12.10/12.04/11.10/Linux Mint 13

If you find troubles installing the latest Nvidia driver on your system in normal mode or having graphics related problems (black screen with white flashing underscore, for example), you can try to install the Nvidia driver via Recovery Mode as described below.

Nvidia graphics problems may not be solved for all users after using this method because it depends on the hardware and software used (graphics card model, kernel version, etc.).

Getting Started

To enter in Recovery Mode under Ubuntu 12.10/12.04/11.10 and Linux Mint 13 or older, reboot your system and hold down the SHIFT key to bring up the GRUB boot menu. When it shows up, select the line saying "Ubuntu... (recovery mode)" and press Enter:

For Linux Mint, select " Linux Mint ... --recovery ...":

Wait a few seconds and another menu will appear. Select "network Enable networking" using your keyboard Down arrow key  and press Enter to enable your internet connection:

In the next screen, select Yes and press Enter:

Select now "root Drop to root shell prompt" and press Enter:

You are now in CLI mode, update your system firstly using these two commands:

sudo apt-get update

 sudo apt-get upgrade

Install now the latest Nvidia driver (currently version 304.43) from PPA using this sequence of commands:

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current nvidia-settings

When you finish the driver installation, exit from Recovery Mode using this command:


Then select "Resume normal  boot" to start your system in normal mode. I hope you find this tutorial useful.

How To Create ISO File From CD/DVD-ROM Using The Terminal - Ubuntu/Linux Mint

In this tip, we will see how to use the terminal under Ubuntu/Linux Mint to create ISO images of CDs or DVDs inserted into your CD/DVD-ROM drive. The command line tool that we will use is dd which allows to make backup copies of your CD/DVD discs and hard drives.

Getting Started

1. Check firstly where your CD/DVD is mounted using this command:


For my system, the CD is mounted as /dev/sr0:

2. I need now to unmount it with this command:

umount /dev/sr0

Replace /dev/sr0 with your own details as displayed in the output of the "mount" command.

3. Create now the iso image with this command:

dd if=/dev/sr0 of=~/image.iso

  /dev/sr0 --> the input that we will read from

  ~/image.iso --> the name of the iso image that will be created (the iso file will be created in your home, but you can set any other path of your choice)

Note: if you are creating the iso image in a system folder, don't forget to add "sudo" at the beginning of the command.

Also, if you want to add a progress bar for the dd command, install the dcfldd package:

sudo apt-get install dcfldd

The command for creating the ISO image will be as follows:

dcfldd if=/dev/sr0 of=~/image.iso

PV also allows to display a progress bar for the dd command. Install it on Ubuntu/Linux Mint:

sudo apt-get install pv

Then create the iso file using this command:

dd if=/dev/sr0 | pv | dd of=~/image.iso
