I have been using ubuntu for about a month now, making the transition from windows. I wanted to try a different Desktop environment then gnome. I used Synaptic package manager and installed FVWM crystal but it didnt automatically switch to the new environment. So in a moment of brilliance i say " Hey maybe i have to delete Gnome and it will enable the new environment." I delete everything that has to do with gnome but it doesnt go away. I still have gnome i just have deleted all the essential programs needed to do anything with the desktop. I cant add new programs, cant use terminal , cant use synaptic. So i figured im screwed. Any suggestions would be much appreciated ,because i am stuck.
