Hello,

Marius Bakke <mbakke@fastmail.com> skribis:

Why is the desktop environment killed?

>From Guix=E2=80=99s viewpoint, the =E2=80=98xorg-server=E2=80=99 Shepherd s=
ervice cannot be
restarted if it=E2=80=99s still running (and indeed, when I run =E2=80=98gu=
ix system
reconfigure=E2=80=99 from my X11 + Ratpoison setup, Xorg is not killed,
fortunately.)  Same for =E2=80=98dbus-system=E2=80=99 etc.

I don=E2=80=99t know what else could be killing GNOME et al.

Thanks,
Ludo=E2=80=99.
