Linux: Install graphical user interface

Choosing the distribution is the most important part for those who want to optimize Linux for old computers, but also on new ones for more power, for those who have chosen the distribution or do not want to change it, the second thing to evaluate in order of importance is the graphical user interface GUI
This remains active at all times of use and will draw the appearance of our system, this makes it a potential bottleneck in scenarios with limited resources

Choosing the X window graphical user interface

Also this choice, weighs heavily on the performance of the computer, most of the computing power is used to run this graphical environment, let's see what may be the best solutions for a dated PC:

1. Flux box, icewm: They are really minimal interfaces, if you are brave and have a very dated computer they are the choice for you
2. LXDE: It is a well made, light and minimal but easy to use graphical user interface without too many compromises
3. XFCE: "Big sister" of LXDE, heavier but offers some conveniences not found on its predecessor, you can also try Mate or Cinnamon, used in the very popular Linux Mint
4. Gnome, KDE:These are the classic interfaces, they offer the most functionality, but they certainly pay the brunt of their completeness

In the gallery above you can see screenshots of these six GUIs to get an idea of what they may look like
In case you don't need it you can not install it, on Linux servers it is usually not used
