Raph, sorry to have confused you with the work terminal. I ran the
pgrep terminal (mlterm)

Should have said the $ that results from a log in

No, the pgrep is there.

No that's exactly what I do. I created a new account, and it has the
same problem of not loading fluxbox

I don't see how, once I've run startx, how to do it again. Fluxbox
seems to think a window manaager already running. I probably should
install a difference manager and see if the same problem occurs with

Not sure I follow this. $ startx starts Xorg. Xorg terminates only
when the window manager shuts own.

Understood. My problem was that I didn't know whether the grey with
Devuan spiral was a default winow manager.

No the last line is exec startfluxbox. Althogh I could install fxce4
to see if my problem persists.

I reinstalled fluxbox to no avail.

Yes that conclusion very useful.
