Hi,
I had 3 working BLFS builds of Gnome desktop over Sysv, but
somewhere between
one week ago and now, gdm got broken and does not start anymore
(begins
stating, but stops with a message "Oh no ! something has gone
wrong, contact a
system administrator" (how helpful !). I have not
been able to get useful messages from /var/log/gdm, but what I see
now in the
logs is that there are messages from the X server, which weren't
one week ago
(I think gdm was starting directly on wayland). Maybe it has
something to do
with this message from the log file:
gnome-session-binary[1370]: WARNING: Falling back to non-systemd
startup
procedure due to error:
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown:
The name org.freedesktop.systemd1 was not provided by any .service
files.
I have no time to investigate more, because I have to leave for a
few days.
I'm around two days out on my SysV system. I should be able to look
into
it a couple days from now.
I think it may be related to one of the updates I did recently. One
suspect could be gnome-desktop. I don't think I updated GDM
recently,
but it could also be gnome-session or gnome-control-center.
If I trust the message, it comes from "gnome-session-binary".
I remember once I upgraded gnome-desktop then seen "Oh no" from GDM.
Then I fixed that by rebuilding GDM.
I've tried that, and even built a fresh system, but nothing worked. Note that I can start
gnome from command line, with startx and "exec gnome-session" in .xinitrc.
Hi Pierre,
I've traced it down to a problem in elogind, and have begun working on a
fix.
elogind is only setup to read one line from the session data in
/run/systemd/sessions. GNOME was using the improper behavior previously,
and was fixed as part of gnome-session-3.34.2. elogind has to be adapted
to read more than the first line of that file:
"# This is private data. Do not parse."
Won't result in a valid UID after all :-)
