Install/reinstall or restore gnome2 on CentOS through CLI.
June 3rd, 2012 by Andrea Matesi 58 ViewsPaint this scenario:
[YOUR BOSS]:”What is this evolution crap?, What is this bluetooth?, What is this pcscd?, What is this GAM-SERVER?" (while referring to a just installed CentOS 5.x dedicated mail server ps output).
[YOU]: end up spending hours trying to remove random "unuseful" stuff & services and loosely remove too much (like I did…), then, after rebooting, you are welcomed by X/twm in all it’s magnificence…don’t panic!
Through the CLI it is possible to (re)install or restore gnome2, just type (as root) the following at a terminal:
yum -y groupinstall “GNOME Desktop Environment”
The next time you reboot, you’ll get your much-desired gnome 2 desktop environment back.
Catch: if, for gosh-knows-why, Gnome 2 still doesn’t start, check "/etc/sysconfig/desktop" contents, and (if empty), add:
DISPLAYMANAGER=GNOME
