Actually we do have a back up desktop in Lx 3. The Plasma5 and LXQt ISO’s also have Openbox. (If you check on the sddm login screen I think you’ll find it there.)
The advantage of LxQt and Lumina is they reproduce what proprietary OS users are used to… I like OpenBox, FluxBox though for their minimalism.
I remember old WMs from the last millenium that I really loved, and which wrere beautiful (even compared to the standards), but I guess they are no more active, such as WindowMaker, AfterStep etc.
all the basic packages essential to the system, including of course those useful for network connection
the installer
language: English only
icewm for a minimal desktop environment
no office stack (libreoffice, calligra, etc.) just a simple text editor similar to kate or leafpad
no multimedia stack (VLC, cantata, etc.)
no graphic stack (krita, karbon, etc.)
no print stack
Post-edit: I don’t know that there would be a big demand for this. It would be typical or our users that no one says much until after a decision has been made.
