I selected fluxbox as the session to load at the bottom of the loading screen, like this photo. However, I no longer have Ubuntu classic or Ubuntu, or anything else. I just have fluxbox, as I removed everything else. Now, logging in just brings me quickly to a black screen which has two lines of text and then brings me back to the login screen. If I use the recovery console, I can start fluxbox, but I won't have any internet.

What solution can be offered so that I can just login normally with fluxbox?
