So do not hesitate to run the config command just to try a different one. No, it does not immediately kill your GUI - this is just about login and WM and I use it with Lunbuntu, XFCE4, Wayland, Gnome, Unity, Ubuntu-X, Ubuntu-Wayland. Right, it is not about installing the whole environment and stuff. Just try to switch the WM (window managers) back and forth. I'd have answered the question ' Switching window manager ?' different:Ī WM (window manager) is something different than a desktop environment! It's like shoes and feet.
