What default console for Linux os?

There is no one-size-fits-all answer to this question. More appropriate questions would be: How do I use my computer on a daily basis? How do I use it for recreation?

Even those questions are tough to answer. First, which variation of Linux are you using? Red Hat? Debian? Ubuntu? Or perhaps you want to mix your own? Each one of the Linux variations has different desktops available to it. Once you decide on a variation (or "flavor"), then you can ask the above two questions about daily basis and recreation.

I use Ubuntu (Debian) so my answer will be about desktops in that flavor. The Unity desktop seems to be touch-screen oriented, buttons on one side. Gnome has been the standard for several years, now with 2 variations: Gnome Shell, which reflects the old Gnome desktop, and Gnome 3, also known as redesigned Gnome. XFCE is a very basic but still very good desktop, lightweight, not too many "bells and whistles," but it gets the job done. MATE (pronounced mah-TAY) is a newcomer, it's very much like the Gnome standard desktop. (I use the MATE desktop on my primary machine, XFCE on my other one.)

The KDE desktop has been around probably as long or longer than Gnome. It's very good, and easy to use and maintain.

You can download the various desktops that are available within your Linux variation and test drive them. This can get tricky; I suggest using a non-production computer that you can wipe and reinstall the OS if need be.

How many flavors does Linux have?
