Alienware Releases its First Linux Running Gaming PC

Alienware, one of the more renowned gaming PC manufacturers, has come up with their first Linux running gaming PC ever. The new X51 desktop PC costs $599 and is available right now.
More powerful variants of X51 are also available.
The specs
The X51 has a 3.3Ghz Intel Core i3 processor, which although weaker than i5 and i7, is still capable of handling stuff. The amount of RAM is set at 6GBs. A 1GB NVIDIA GeForce GTX 645 graphic card and 1TB of hard drive storage are there too. The desktop runs on Ubuntu 12.04 LTS. The unit itself is 12.5 inches high and 12.5 inches long. There’s an optical drive in the pack as well.
Now obviously, with Linux, you won’t be able to take complete advantage of the gaming hardware due to a desperate lack of gaming titles. Currently there are 25 titles available on Steam, the popular gaming platform but many more are on their way and compared to that Windows’ gaming library is light years ahead.
However, there is a Windows 7 running equivalent of this desktop too but unfortunately that costs a full $100 more than this system. Another solution though, which most people will find a lot more attractive is to uninstall Ubuntu and put Windows on the PC yourself and enjoy the latest gaming titles. Given the fact that Windows’ gaming library is outrageously large (and Ubuntu’s ridiculously small), true gamers will mostly find this route to be the best.
As more and more Linux-based systems have started to come out though, it has started to become clear that the OS isn’t a small, worthless thing in the PC industry anymore. In fact, If the customers get interested, we might even be seeing a new revolution in the PC industry, but its just too early to predict anything right now though.

Checking Computer Specs in Linux

 

Something you always want to do on a computer, even if only once, is to check its hardware specifications, that is:

• how much RAM do I have?
• how much hard disk space do I have?
• how “fast” is my CPU?
• how much RAM does my graphics card have?

Of course most modern GNU/Linux desktop environments like Ubuntu usually come with some kind of graphical tool to find this information. GNOME’s System Monitor program should provide at least some of what you’re looking for. The information here is more for when you’re staring at a blinking cursor on a black screen trying to remember what the command was to show information about the CPU, RAM or Graphics Card.
This is the third time I’ve had to go on an internet search quest to remind myself how to do this in a Linux terminal. To save myself the trouble in the future, I’m writing down the commands here and if anyone else finds it useful then that’s great, and a second bird is figuratively killed!

How much RAM do I have?

I’m not sure if there’s another way of doing this, but dmidecode is a tool for dumping DMI information in human readable form and can be used to show information about your RAM devices like this:

# dmidecode --type 17

How much hard disk space do I have?

To list your partitions and their information, including size, you can use the -l option on the fdisk command:

# fdisk -l

It needs to be run with root privileges. With no arguments it describes all the devices found in /proc/partitions but you can also specify a device name, as in:

# fdisk -l /dev/sda1

How fast is my CPU?

You can find a lot of information about your CPU, including the number of cores and the clock speed in the /proc/cpuinfo file:

$ cat /proc/cpuinfo

How much RAM does my graphics card have?

It will take 2 steps to find out how much graphics memory your computer has. The lspci command is used to get information about PCI busses and devices connected to them. We need to search the output of the command for something VGA compatible:

$ lspci | grep VGA

That should return a line starting with a number. You use that number to refer to the graphics device to get info for it:

$ lspci -vs 01:00.0

The -v flag is for verbose output and the -s flag is for specifying the domain (the number from the first step). Among the information here will be the amount of memory, with the size written in square brackets at the end of the line.

A brief mention of that other OS…

I suppose the methods for the ubiquitous Windows operating system are just as obscure but having used it for years they probably seemed normal just because I was used to them. WinKey+Pause|Break was the shortcut for showing the properties of “My Computer” where you could check your RAM and CPU specs. WinKey+E was the shortcut for Windows Explorer, which would open at “My Computer”, showing you the sizes of the different partitions you have. Even less people would think of typing “dxdiag” at the run prompt (WinKey+R) to start the DirectX Diagnostics Tool, which gives you information about your graphics card. If you were wondering how you check your specs in Windows, I guess I just covered that too!
Speaking of other operating systems, with its shared UNIX roots, I’d be interested to know if these commands work on the Mac OSX operating system too!

A script to automate the process

Shortly after writing this post I realised it might be nice if there was a shell script that did all the above things for you and output it all in a nicely formatted way, so I wrote one!
You can download the script file here or read the source code here.
