No, but it asks for it every second and fills up the log with cannot connect.

This was only the core of the problem.  There is a configuration
option to disable dbus, it's off by default and you need to write
a Xorg.conf.  The automatism is broken and will not be fixed, because
"you don't need an Xorg conf, Xorg configures itself".  I forgot how to
write a Xorg.conf manually because I haven't done in 15 years, so I
asked how, then I got the answer: use -configure.

I understand that this is the gentoo-aproach and you like that
system.  But I did choose to use devuan.

Actually I didn't ask this in the first place.  Brocashelm did, and I
made a suggestion.

And regarding the "quotemarks".  Yes.  Probably this somebody will
be me. 

Wasn't the title of this subforum "freedom hacks?"   I am sick of
software I have to recompile everytime a new version is out,
because someone decided I now need to use pipewire.  Oh wait.
Somebody made a preload-library and now I still can use alsa.

Great.  I don't want one.  I want it switched off.  There are other
ways to do whatever it's good for, most likely /bin/true.

@greenjeans:

I really don't get what's so funny.  There are a lot of places in
the world where you get in trouble for something on your
computer, perfectly legal three years ago, and the number of
this places is growing.

So it's fine if you are embarassed by porn and not by lack of
credit, but there is already stuff you can only do online that
requires you to type in - for example - your SSN (maybe not it
in the USA, i don't know about them.)

There were complaints by the X.org people about Enricos (the developer
behind Xlibre) patches, they claimed it broke stuff.  Are these complaints
for real, is there something obviously not working with Xlibre, or is it just
politics, as in "used bad word" or "makes it difficiult to force
$unwanted_new_shiny_technology onto the user"?

Gr, Brgs

Now I realize, that the question was wrong:

Appcompat is not installed, and I don't know in which debian
package it hides, or if there exists another way to install it
without using the eclipse / gradle ecosystem.

Thanks alot!
