The following is available: Wireless Keyboard and mouse combo NXQ NOTE: The NXQ is a miniPC which runs one of the following OS's: Nitrux OS 2.15 AOSP 4.4 CyanogenMod 11 Now, you may have noticed that the NXQ can come with Nitrux OS. Nitrux OS is available, but to see a version without buying the NXQ, you need VirtuaBox. The Nitrux company has created a virtual system of the Nitrux OS already installed in a VDI. NOTE: The VDI is a Virtual Disk Image used by the VirtualBox application. The Nitrux OS image has the following system requirements: (Log in to hide this advertisement) A Linux/Windows/OS X computer 6.5 GB available disk space 1.7 – 2.0+ Quad-core x64 CPU 2 GB of free RAM 128+ of free VRAM Network Adapter To download VirtualBox if you do not have it, go to “https://www.virtualbox.org/wiki/Downloads”. The Nitrux OS VirtualBox image can be downloaded from http://nitrux.in/solutions/software-solutions/nitrux-os/#. There is a box towards the bottom of the screen which says “Try It”. Click the box and an End User License Agreement appears. Scroll to the bottom of the license and click “Accept” if you agree to the License. You should be prompted to download the file, or if your browser is set to automatically download files then it will start. Once downloaded, you should have a file called “nitrux_2_15_VM.7z”. Extract the contents of the file where you want to store it. The archive contains two files: Nitrux 2.15 x64.vbox Nitrux 2.15 x64.vdi Once extracted, select the “vbox” file and open it with VirtualBox. In VirtualBox a few settings may need to be changed depending on your system hardware. To determine which settings may be invalid, open the “Settings” for the Nitrux machine. At the bottom center of the window a message may say “Invalid Settings Detected”. Hover the mouse cursor over the message to see which items are invalid. Two items are usually the issue. The first is the Base Memory and the second is the number of CPUs in the system. Adjust any necessary invalid entries until the message disappears. Once the message is gone, “Start” the machine. At the Grub screen, highlight “Ubuntu” and press Enter. At the logon screen, a red circle will appear with the username of “Nitrux S.A.” under it. Click on the red circle and then enter the password when the password box appears. The password is “nitrux” and should be all lowercased.

There are also animated wallpapers which can be used on the desktop. The Nitrux OS is based off Ubuntu and is very system intensive and may be slow for systems with less resources. Keep in mind that the machine may be slow if you have little resources, even if they are less than the system requirements.
