Hello, I have recently installed the gnome desktop to my linux mint. I had it to where it booted directly to the terminal. when I typed startx it didn't know what enviornment to use so it used a basic black screen with a mouse so I went in and made it to boot back to normal to the login screen. is ther a terminal cammand to specify what desktop session I want to use so I can have it go back to booting to the terminal?
