Looks as if everything was started.

Could you share bits of /var/log/messages starting from the line that
reads “syslogd (GNU inetutils 2.0): restart” (the last boot)?  This
could contain sensitive information so you can redact it or share it
privately if you prefer.

Oops, I meant <https://issues.guix.gnu.org/55444>, which is now fixed.

It works fine in ‘guix system vm’.  :-/
(Same for you?)

So it could be a stateful issue, such as stale files in /var/lib/gdm.
One way to test that hypothesis would be, for instance, to run:

  sudo mv /var/lib/gdm/.cache{,.bak}
  sudo herd restart xorg-server

Thanks,
Ludo’.
