I am running Ubuntu Server 8.04. Do I really need all five getty tasks running? It automatically starts tty2 through tty6.
I know they don't consume a lot of resources, but they do consume limited space on the window I keep running to view the "top" program. If at least a few of them were gone, all my processes would fit within one screen.
If I never need a serial port, can I disable some or all of them? I do not know if they are required for the terminal to work, or to allow ssh access, which is all I really ever use.
