In my experience the howtouselinux.net review let me to save a lot of time because I was able to focus my tersts just on the two Distros that seemed to have the right prerequisites for my old eeepc 900: Peppermint OS and Macpup. Recommended!
Bodhi: a less known but powerful Linux distribution
If you are looking for a light Linux OS for your computer you can test Bodhi Linux. This specific Linux version, based on Ubuntu, utilizes the enlightenment graphical interface. For this reason Bodhi is particularly indicated also to give new life to computers with no updated hardware.
The graphical interface is really “zen” or rather clean, easy to navigate but complete. We tested the 32 bit version and it was a smooth experience also if we used a single core pc with 2 GB of RAM.
Before testing Bodhi you have to keep in mind that this Linux OS is really user oriented. It means it has just some few pre-installed programs and so you are free to customize it as you prefer. Last thing to remember is that Bodhi is a semi-rolling distribution ans so it will be updated in occasion of Ubuntu Long Term Releases (LTS). Try it, it is worth a chance!
Solve audio troubleshooting on Ubuntu and start planning to migrate to another Linux OS
It was just a simple system update which dropped off audio on my Ubuntu 12.04. It was really strange to admit that I had experienced a crash (better: an audio crash) on a Linux but the 12.04 Ubuntu actually caused similar problems to a numerous bunch of long-term aficionados around the world.
The real problem with the last Ubuntu versions is that this OS is not supporting properly “old” hardware as it did previously during so many years. Reading some other bug reports on the web I discovered that these audio troubleshooting crashes happen principally to “old” IBM ThinkPad and Dell. I hope Ubuntu developers will consider to solve immediately these kind of issues or many users certainly migrate to other Linux version.
In any case the best and complete guide to solve audio troubleshooting has been developed by Ubuntu itself. The guide is very detailed but, if you want to definitively solve this bug, you have to spend more or less 40 (forty…. sic!) minutes and follow all the 17 (seventeen… sic!) steps.
In my case the audio was back after the first step and I decided not to follow the other instructions but the audio troubleshooting comes back, more or less, every two months. Just to you if you want to spend 40 minutes only one time or a couple of minutes every two/three months.
When I consider all the problems I had with Ubuntu on “old” hardware starting from the 12.04 version, my advice is to start thinking about a migration to another Linux OS. I am testing some Ubuntu alternatives and in the next weeks I will post something about the tests I’m doing on old laptops. Stay connected! 
The good third choice: MATE desktop environment. The traditional but rock solid solution for the Unity unhappy users (when also Gnome fails)…
My first Linux OS was a Knoppix but I had so many problems with the hardware drivers, the LAN configuration and the monitor settings that I was really discouraged. After many tests I decided that Ubuntu was the right OS for my notebooks and I continued to use it without any particularly matters till Unity.
Unity is nice to see, intuitive but if you use your OS in a stressful way (I mean doing three or four different tasks all together: reading emails, talking with Skype and writing on LibreOffice), you spend too much time looking for the icon you need to launch the right program. The vertical monitor space has not enough room to visually show all the icons related to programs I use everyday. Surely this is my personal matter but I actually prefer the “old” graphic interface. For this reason I decided to install Gnome 3 but my vetust IBM Thinkpad crashed a couple of time in a week.
To my surprise also the Gnome Classic option encountered some crashes due to the amount and diversity of the software I installed on my laptop during the last years.
As usual, after some web searches I found a solution: MATE. This particular desktop environment is a fork of Gnome 2 and it really looks very intuitive and easy to use. If some software conflicts with the MATE environment, a pop-up message will appear on your sceeen and, if you have the patience to read the Details contained in it, you will able to solve your problems. In my particular case (don’t ask me why) it helped me to focus my attention on Conduit which caused the crashes on Gnome.
To easily install MATE, on almost every Linux distribution, you can read its wiki dedicated page or directly follow the below instruction if you use Ubuntu 12.04.
– open Terminal and type these command lines:
sudo add-apt-repository "deb http://repo.mate-desktop.org/ubuntu oneiric main"
sudo apt-get update
sudo apt-getinstall mate-archive-keyring
sudo apt-get update
sudo apt-get install mate-core
sudo apt-get install mate-desktop-environment
When the Terminal finishes all the upgrade stuff, reboot your Ubuntu 12.04 and select MATE on the login screen (click on the upper right “gear” and choose MATE).
That’s all! Have a good week!
