Mobian other Desktop Environments

[canaac]

Can xfce installation be done directly from mobian + phosh?

Yes, that's what assumed you had done at first. You can apt install lightdm, onboard and xfce4 desktop. Edit the lightdm greeter and then reboot. It won't have the handy customisations found in the recipe but you will have a full resolution desktop to play with.

I will try what you tell me.

Thank you very much for your help.
