How to Install SteamOS in VirtualBox
================================================================================
**The following tutorial will teach all Linux users how to install Valve's brand new SteamOS GNU/Linux operating system in a virtual machine, using the powerful and popular VirtualBox software.**
As you already know, the [SteamOS Linux has been officially released on December 13][1] and is based on Debian GNU/Linux operating system, using GNOME as its (optional) desktop environment.
SteamOS is very easy to install if you have the right hardware components, which involves a UEFI-capable computer with a powerful video card for playing games. However, as Valve did not publish an ISO image of SteamOS, many have encountered difficulties in installing the system.
The following tutorial is comprised of two important sections, one that helps you create an ISO image from the SteamOSInstaller.zip file provided by Valve, and a second one where you learn how to install SteamOS in VirtualBox if you don't want to install it on a real computer.
To get started, you need to have a working installation of the latest VirtualBox software. Also, you need to install a software called [GNU xorriso][2], which you'll use to generate the ISO image from the SteamOSInstaller folder.
### Step 1 Generate SteamOS ISO image ###
[Download the SteamOSInstaller.zip from Softpedia][3], save it on your home folder, and extract the files. A folder named “SteamOSInstaller” will be output. Now, open a terminal in the home folder and execute the following command:
xorriso -as mkisofs -r -checksum_algorithm_iso md5,sha1 -V 'Steam OS' -o ~/SteamOSInstaller.iso -J -joliet-long -cache-inodes -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot --efi-boot boot/grub/efi.img -append_partition 2 0x01 ~/SteamOSInstaller/boot/grub/efi.img -partition_offset 16 ~/SteamOSInstaller
The SteamOS.iso file will be generated in a few seconds on your home folder and will have approximately 1GB in size. That's all, you can now proceed to the next step.
### Step 2 Install SteamOS in VirtualBox ###
Considering the fact that you already have a working VirtualBox installation and that you already know how to use the software, you must create a new virtual machine with UEFI support. On VirtualBox's main window, press the New button to start the process of creating a new virtual machine.
In the name field type SteamOS, choose Linux as the operating system type, select Debian 64-bit from the Linux version drop-down box, and click Next to continue. Set 1024 or 2048 for the memory size (this depends on how much physical RAM your computer has), create a virtual hard drive of VDI file type and fixed size with 15GB. Click the Continue button and wait for the hard drive creation process to finish.

*Set the memory size*
Now that the virtual machine has been created, lets make a few adjustments for the SteamOS operating system. Go to Settings, click the System section in the sidebar, and uncheck the “Floppy” entry from the Boot Order box, and make sure you check the “Enable EFI (special OSes only)” option.

*Enable EFI and remove Floppy*
Next, click the Display section in the sidebar, set the Video Memory to 128MB, and check the “Enable 3D Acceleration” option. Then, go to the Storage section in the sidebar, click the “Empty” line under “Controller: IDE” and add the SteamOSInstaller.iso image generated in the first step by clicking on the small CD icon next to the CD/DVD Drive drop-down box. Click OK when done.

*Set Video Memory size and 3D acceleration*
And now, lets start the virtual machine by pressing the big “Start” button on the main window. You will immediately see the SteamOS boot screen. Just press Enter with the “Automated install (WILL ERASE DISK!) option highlighted, sit back, and relax until the system is installed, which will take some time, depending on your computers specs.

*Prepare to install SteamOS*
Once the installation process is finished, you can close the virtual machine, remove the ISO image from the Storage section, and boot into your new SteamOS. But, before you start exploring SteamOS, you will need to install the VirtualBox Guest Additions. To do that, start the SteamOS virtual machine, select the second entry on the GRUB boot loader screen (Recovery), and type the following commands when you hit the SteamOS command-line prompt:
![SteamOS boot loader](http://i1-news.softpedia-static.com/images/news2/How-to-Install-SteamOS-in-VirtualBox-409363-9.png)
dpkg --get-selections | grep nvidia
apt-get purge <name of the packages outputted by the above command>
rm /usr/share/X11/xorg.conf.d/55-nvidia.conf
dpkg-reconfigure xserver-xorg
Go to Devices and click on Insert Guest Additions CD image. Download the Guest Additions image when prompted, mount it and run the following command:
sh /media/cdrom/VBoxLinuxAdditions.run
Wait for the Guest Additions to install its drivers and reboot the virtual machine with the following command:
shutdown now -r
![SteamOS command-line shell prompt](http://i1-news.softpedia-static.com/images/news2/How-to-Install-SteamOS-in-VirtualBox-409363-10.png)
*SteamOS command-line shell prompt*
The virtual machine will reboot, let it boot into the SteamOS and, when you arrive at the login prompt, use desktop/desktop or steam/steam as the username and password to login. Do not hesitate to comment below if you encounter problems during the installation.

New Ubuntu 14.04 Icons Are Drop-Dead Gorgeous, Might Not Arrive in Desktop Version
================================================================================
**Canonical is preparing a facelift for the Ubuntu 14.04 LTS and the new icons that are being designed right now surpass anything that's been done before.**
During the last UDS (Ubuntu developer summit), James Mathieu, a designer who has been working fervently on a new look for Ubuntu, presented a set of icons that were simply beautiful, for lack of a better word. Now he is showing us in much greater detail the work he has been doing.
“This projects main goal is to create a single modern, high-resolution icon theme for desktop and touch devices that can adapt to various screen densities and reinforces the Ubuntu user experience. We want our icons to express our values and convey Ubuntus personality in a unique way.”
“We already had mobile icons for the applications and symbols, but, because they evolved over time without strong guidelines, did not form a consistent set. On the desktop, even though the style is clean and consistent, the icons looked dated and needed to be replaced too,” said James Mathieu in a post on the official Ubuntu website.
Canonical's goal right now is to update the old icons for all the platforms which now include phone and tablet, and get them up to today's standards, without losing their identity. Users must be able to identify an Ubuntu system just by looking at the icons and nothing more.
The old set that has been used so far doesn't look half-bad, but the ones that have been presented so far are drop-dead gorgeous.
“Weve been working on this on-going project for the past year. Weve done extensive research on the subject with a focus on learning how best to classify the icons; and weve gone through several design iterations and explorations,” [also][1] said Mathieu in his post.
These are not the final versions of the icons and the design might change. Theres also a chance that the new icons might not be ready in time for the desktop version, but we can only hope.
