SSH from Windows PC into PinePhone?

[zetabeta]

But how can we from there start the graphical user interface or posh shell of the PinePhone?

is the question more like, how to have graphical connection to the pinephone?

there is "wayvnc", but is it available in postmarketos. i have used in manjaro though. on a windows side, i don't know which client program works.

"rc-service" can start and stop background processes. usually in others it is "systemctl". systemctl can be used to start and stop graphical system. but it seems that phosh was already running.
