I have an working ubuntu server 6.10 with desktop. I want to upgrade my server to Ubuntu 10.04 LTS now. I don't want the server to be booted to GNOME desktop, but still i want GNOME desktop be there so that i can start it when needed. By default ubutnu should boot in CLI. How cam i do that? is this a good way for server installation? or any other recommendation please.

PS My server is connected to local network and not to internet.

Thanx & regards
