This is probably the same problem that arch has on WSL. The fix there is to install dbus-x11 from the AUR. On Mon, Feb 17, 2020, at 20:50, Mgr. Janusz Chmiel via arch-general wrote:

Dear specialists, Ihave tried to use Arch Linux on Android device thanks to Proot, Termux and thanks to The Arch Linux script by Mr Rausty, which is available on Github.

Unfortunately, I have found out, that there is very complex problem with Dbus. Many apps, which require inter process communication work only, when I type. dbus-launch app name But even when I start Dbus and some app by this way, some more complex applications not work. There are more rreasons. Firstly in strictly userspace oriented Linux environment, Arch Linux do not support to run services. So Dbus can not be started as A service. Is there some technique, which can allow me to use Dbus by more efficiently? Or in such non ssstandard environment, there is no way how to setup The system so Dbus would be used more efficiently.

What can I allready use? Orca screen reader and many GTK apps including Gradio. But again, some apps start dbus-launch with some command line option and system refuses to start Dbus so app can not commit the changes to Gconf database for example.

Any help will be very appreciated. Thank you for yours patience and for yours advices. With kindness regards. Janusz Chmiel
