HI!

I am trying to set up FreeNX (one Remote X desktop software) on my VPS (CentOS 5.5). I have googled and found several different tutorials.

One tutorial says:

yum  groupinstall “X Window System”
yum groupinstall “GNOME Desktop Environment”

Another says:

For a KDE desktop, do "yum install -y kdebase". 
For Gnome, do "yum install -y gnome-session".

I want to know:

  1. Is “X Window System” optional? When I googled, it says “X Window System” is the backbone of KDE and GNOME. Some tutorials say “X Window System” eats lots of computer memory and it is optional if you have small computer memory. I am confused.

  2. If I am going to install Firefox and extensions on my VPS, is yum install -y kdebase enough? Should I use yum -y groupinstall "KDE (K Desktop Environment)"?

Thanks a lot!

Both KDE and GNOME run on top of X Windows. KDE and GNOME are desktop environments whereas X Windows is the windowing manager.

  • But you still havent answered my question. Is `yum groupinstall “X Window System”` optional here? Why do some tutorials say it is optional? Thx! – DocWiki Feb 02 '11 at 21:55
  • If you want a graphical desktop environment, then you need to install X Window system and then install GNOME or KDE. – yasouser Feb 02 '11 at 22:13

    Many years have passed, but to answer your specific question; yes, installing “GNOME Desktop Environment” will automatically install the “X Window System”, that's why some of the pages would say 'yum groupinstall “X Window System”' is optional. – Siddu May 17 '19 at 13:39
