Start 2016 with a bunch of unusual Linux OS!

linux-distributions-to-look-forward-in-2016

What’s better than testing? For me nothing!

For this reason, let me introduce some “unusual” Linux distribution proposed by Jesse Afolabi @Jesseflb via Techmint.

VeltOS and PapyrOS are based on Arch but the last one is in its pre-alpha testing so it’s not suggested for beginners.

Moreover, we may decide to begin 2016 with Korora that is still one of my favorite projects also after so many years since the first release.

Last but not least, we have Solus OS 2 that it is not the most Linux distribution I tested but it is stable and really well built.

Happy 2016!

How to install Ubuntu 12.04 on old computers with non PAE CPU

When I tried to install Ubuntu 12.04 on an old ThinkPad X40 I was surprised to discover this warning on my screen:

This kernel requires the following features not present on the CPU:
pae. Unable to boot - please use a kernel appropriate for your CPU.

In few words I wasn’t able to install Ubuntu 12.04 because the kernel on Ubuntu 12.04 was not supporting my CPU and I was really upset because I have always promoted Linux distributions as the most versatile and appropriate OS to keep using “old” hardware.

Sincerely, as described in an older post, I previously decided to install MATE desktop environment because the graphic cards on many laptops didn’t support Unity and Gnome 3 but this was the first time I had to renounce the installation of Ubuntu. I didn’t want to surrender to this difficulty (that appeared to me as a bug)!

First of all, I discovered that pae is “a feature to allow 32-bit x86 processors to access a physical address space (including random access memory and memory mapped devices) larger than 4 gigabytes“. After I clarified this point, I was not sure that my processor was totally inadequate to support Ubuntu 12.04.

After some web surfing I discovery that there are two easy solutions to avoid this problem.

1 – As first solution you can install Lubuntu (my choice) or Xubuntu on your computer then you can install the ubuntu-desktop using the Package Manager.

2 – If you prefer not to use the Package Manager you can install Ubuntu 11.04 or 11.10 and then upgrade Ubuntu to 12.04.

More in general, it is also possible to assume that if you have a non PAE CPU, your hardware could not be able to support the Unity desktop. For  this reason you can keep your Lubuntu – Xubuntu (based on the light but effective LXDE desktop) or switch your desktop environment to Gnome (the Classic, of course) installing the gnome package instead of ubuntu-desktop.

In any case, if you want to know if your CPU supports pae you have to open a Terminal and type:

grep --color=always -i PAE /proc/cpuinfo

If something like “flags: fpu vme de pse tsc msr pae mce cx8…” outputs on your Terminal, you have a pae CPU otherwise your CPU doesn’t support pae.  AddThis

Lubi: the Linux based Ubuntu Installer

LubiLubi is a useful tool for all people who like to experiment different Linux OS on their PCs. In particular Lubi has been thought to let you install Ubuntu in just few clicks and without risking annoying “secondary effects” on your computer. In our Linux Page (in Spanish) we have posted a small but effective review with all the necessary links to the Lubi project and we have also listed all the Linux OS (PCLinuxOS 2007 32-bit, openSUSE 10.2 32-bit, Gentoo 2007.0 32-bit, etc..) already tested for a safe -Lubi- use. We strongly recommend Lubi for all users who want to deeply test Ubuntu (and its features) without starting from the Live CD. AddThis

Wubi: one of the best Ubuntu installers for Windows users.

Wubi HomepageToday, in our Linux page we have posted a brief review about Wubi: a simple and effective Ubuntu installer for Windows users. With just few clicks you can easily install Ubuntu without modifying the partitions on your pc (for this reason there are no -or very low- risks of “fatal errors” for your computer). All the Ubuntu files are stored in just a single folder so it is very simple to uninstall Ubuntu if you decide not to use it anymore. In few words, Wubi allows Linux beginners to try all the positive features of Ubuntu without risking undesirable secondary effects. Recommended! AddThis
