hello, It is a long time since I fiddled with the display. is buster. there are the names display manager which is lightdm desktop environment which is mate and window manager which I think is part of mate
If I want to change desktop environment do I need a window manager ? I'm not seeing anything looks like a window manager in output of "ps ax" How do I change desktop environment ? Is it "update-alternatives --config x-window-manager" just asking because I don't want to bugger it up mick -- Key ID 4BFEBB31
