I'm wondering if anyone can tell me how I might switch my desktop environment on a workstation that I do not have admin access on. The machine is running Redhat Enterprise Desktop v3 and there are a few alternative desktop environments I can choose at the login screen, but I would prefer to use Gnome or KDE. I'm fairly certain Gnome is already installed on these machines, as I've seen other users using it. There are also some directories present in my home directory like .gnome, .gnome2, .gnome3 so I have a feeling it is on the machine, I just don't know what file(s) I need to edit so that I can use it. Any suggestions?

P.S. Sorry I know this question gets asked a lot, but after searching the forums and all over Google I can't find a response that fits my situation!

You dont need admin priviledges for changing desktop environment, before logging in click on sessions and select gnome/kde/xfce to change desktop environment and then login

Edit: If the deskotp environment you want is not there in the login screen then it is not installed, the directories you see could be due to some program installed that is part of gnome with full install of Gnome Desktop environment
To install you will need to be root

Yeah it's definitely not in the list at login...

I'm sure I'd need admin access to install Gnome though...which also doesn't explain why other users are able to use Gnome
