Comparing the Librem 5 USA and PinePhone Beta

[guenther]

I noticed an "X" button on the Librem screen, but not on the Pine screen.
Was this button present on the Librem 5 from the very beginning, or did you enable it by yourself?
In the case of the latter, which Gsetting is that?

In "dconf editor", go to "org / gnome / desktop / wm / preferences / button-layout" -> use default value ("appmenue:close")

On my PineTab it will be set back when docked -> undocked
