Hi Simon,

I am a desktop opensuse user and I believe they have a very supportive
community, I'm not involved but that has been my impression.

a quick search led me here:
https://lists.opensuse.org/opensuse/2009-11/msg00383.html

which I think is related.

furthermore this may help:

Honestly, I think its a bit quirky that a system wont work without a
monitor but I have to point out initially you said that it would not
get to the desktop.  So it is booting fine presumably.  The command
line interface is usefull for many tasks.
 
Since you mention screen auto detection, I have seen mention of saving
a file with EDID info in it.

another quick search and take this for example:

 http://kodi.wiki/view/Creating_and_using_edid.bin_via_xorg.conf

All of this though requires some sort of configuration, either from the
command line or from a text editor ( I think ).  As I mentioned before
the common case is that people will login to a headless machine via
ssh.  This can come with additional difficulties.


"half a booted machine doesn't make sense"

Thing is that your computer is telling you the same thing.

"that might be a workaround but i think we need to get that fixed."

You may have some luck at this mailing list or other xorg mailing lists
as well, I really don't know.  From my end though, this is not
something I am capable of.

good luck and,

Have a good day,
