This document describes how to install Gnome Desktop environment onto an Oracle Linux 6.x system.
1. On Oracle Linux 6.x, Gnome yum group is known as “Desktop“, which was “Gnome Desktop Environment” on Oracle Linux 5.x. Thus, to install Gnome Desktop Environment on Oracle Linux 6.x use the below command:
# yum groupinstall "Desktop" "Desktop Platform" "General Purpose Desktop"
If the packages need to be re-installed, use the below command:
# yum reinstall "@Desktop" "@Desktop Platform" "@General Purpose Desktop"
2. In case X session can not be started up with “startx“, generate a configuration file /root/xorg.conf.new by the command:
# Xorg -configure
3. Check whether X Window could work fine(this brings up X Window simply, just only with “grayscale background and simple mouse pointer”):
# Xorg -config /root/xorg.conf.new -retro
4. And copy it onto /etc/X11/:
# cp /root/xorg.conf.new /etc/X11/xorg.conf
