I decided to upgrade my home server to Ubuntu 11.10 from 10.04. Instead of upgrading to the server version, it upgraded to the desktop version, or something similar to it. I assume this is because I had GNOME installed to manage certain features through VNC (Linux noob here). So how do I get it to stop booting to the desktop and get rid of all the additional GUI stuff it installed with the upgrade?
remove all desktop environments you may have installed, by using "apt-get remove" command. However, thats not the only thing you will have to consider. A server system has a different set of configuration or way of doing things. For instance, a server almost always requires a higher usage of swap-memory as overall performance is more important. On the other hand, relatively less swap memory is needed by a desktop system where quick response-time is more appreciated by the user. You can check the "swappiness" setting of your Linux kernel by issuing the below command in the terminal:
