On Raspberry there is a message “Screen is too small to setup…” when installing Manjaro ARM Gnome on a setup with the official 7" touchscreen.
This was not the case time ago with ARM Xfce I think.
It would be nice to optimise the installation for smaller screens like it.
It is still possible to install it without seeing the bottom of the screen. When I push Win key, I can see the whole screen with the navigation. So I used Alt+N for Next etc. to install it
