We have in our Company SysAdmin so damm stupied and lazy. Everytime I ask him for a Redhat Virtual Machine(VM),He just deploy a ready template with GUI and lot of package,a lot I think he just install every damm RPM package in redhat.
Beside security issue and need of patch which I never ever saw him doing it. I was hoping to conserve resources(Memory/Disk). As most of you know tha redhat use GNOME Desktop Envirement.
My Question here can I disable/enable Gnome whenever needed without system down(No another reason for SysAdmin to hate me).
Here what I found on the internt
yum groupremove gnome-desktop : Quit not option to remove GUI completly since we need it for some mission(couple of times per year).
Edit /etc/inittab file to replace runlevel from 5(multiuser with GUI) to 3 (multiuser without GUI).Although the file contain instruction to diffrent manaer of doing it but I suppose it the same.Well, first it didn't work I still get GUI whenver I connected with XRDP,second it involve downtime for rebooting.
Stop GNOME Desktop Manager(gdm) service,still the damm GUI.
telinit 3 or init 3 to change runlevels , I even don't what the result.It damm close all SSH session VM is still up (ftp working).Now I have to ask SysAdmin for help that mean work he will really hate me , thanks god it was lab VM or I am dead for sure.
So I am at Deadend,anyone encountred this issue,It will be really nice if redhat folks share their experience.
One last thing , I thought to remove gnome and install LXDE is redhat would support that.
