Choosing the session/desktop without login window
Is there a way to choose your desktop environment without the login window (like right from the yboot prompts or other terminal ptions, or from a live cd, or...)
hat's because I have logged out fro my regular Xubuntu session and logged in with a Gnome/Open... session. Now I have an enpty desktop with nothing running, no menus, no panels...
And, as I have choosen to log in automatically, I never have the login window to choose Xubuntu again...
Any help, please?
Linux Mint 17.3 running on my AMD A8-6600K desktop; .Ubuntu 15.10 running on a Intel i5 6200U @2.30 GHz laptop
