I setup an Ubuntu 10.04 server which has several developers on the box. I have been ask to add a gui to the server. Only one developer want the gui to start when she logs in(runlevel 2 with a GUI). I am used to seeing an /etc/inittab file which I cannot seem to find under this Ubuntu version. So once I get the GUI (lightdm/GNOME and etc.) installed, how do I set up just this user to have the GUI to load only for this one user and not the rest?
