Subject: Re: gnome-3.16.x without systemd

I came across your post by chance. To answer your question, it is indeed possible for GNOME 3.16 to 
work without systemd.
I have actually been maintaining a patchset that reintegrates support for Session Tracking and 
Power Management.
A recent version of the most directly related files can be found here: 
https://bugs.funtoo.org/browse/FL-2485
I have a newer version but I'm not quite ready to share it.
If you let me know what operating system you use, I may to be able to help you expedite matters.
In fact, if you use Gentoo or Funtoo Linux you can be using GNOME 3.16 without systemd as fast as 
you can compile it.



Thanks for the positive feedback.

I'm using the 64-bit version of tinycorelinux on which I have gnome-3.10.x working without problems.

I've compiled everything for gnome-3.16.x, but cannot post the various extensions (packages)
to the tinycorelinux repo as gnome-session will not run.
As posted, gnome-shell fails to register with gnome-session, but without any error messages to go on, 
I'm unable to fix things.
I had a quick look at the site you mention, but I don't see any patches that stand out as being 
likely to fix my problem?


I am not actually familiar with tinycorenetwork but what I do know is that GNOME 3.16 should actually 
work as-is
(although with reduced features), if you don't use GDM (as in 3.16 ConsoleKit support was removed)
and if you force clutter to use the X11 backend (as the other backends require systemd, as far as I can 
tell).

My patchset is further down on that page under the attachment section.
Here's a direct link: http://files.mirthil.org/dantrell-portage-overlays.tar.xz (mind, this will only 
stay live for a while longer).
You will mostly be interested in any package that applies a *restore-deprecated-code.patch file
but you will also want to look at what configure options are being passed regarding consolekit and 
systemd,
especially if you intend to use GDM. Only a few packages not in that attachment are not very relevant 
to your purposes.

You wouldn't by chance be using ConsoleKit2 (any version greater than 0.4.6)?
Because when I tested GNOME 3.16 against that, I believe things went similarly haywire.
Also, if you manage to things working but find that native applications don't launch/work,
double check that clutter is using an appropriate backend as I mentioned earlier.




Thanks - to answer some of your questions:


1. I don't know what backend clutter is using, but I don't get any clutter errors and using 
CLUTTER_BACKEND=x11 doesn't change anything.

2. I'm not using gdm.

3. I've tried with both consolekit-0.4.6 and consolekit2 and neither give any error messages.

I already reverted the consolekit changes to gnome-shell-3.16 and applied your revert patch to 
gnome-settings-daemon,
but unfortunately this did > not help.

In general I compiled the various packages against upower-0.99.2 except where they would not 
(telepathy-mission-control)
and against consolekit. > I don't see any particular configure switches in your tarball that I've missed.
I have not compiled gnome-bluetooth-3.16 as the version of udev in tinycorelinux is too old for this,
but other than that everything I know of is present.

I'm starting gnome-session with a wrapper script:

ck-launch-session dbus-launch --exit-with-session gnome-session2 --autostart=/usr/local/etc/xdg/autostart 
--debug

..which gives the attached output - as you can see there's nothing to indicate why gnome-shell fails to 
register
and I'm unable to get any debug output from gnome-shell.

It's possible I might be missing a runtime dep as opposed to having a consolekit problem,
but without error messages it's impossible to tell.


I took another at things, including the logs you provided and I think that your problems have nothing
to do with any patches (missing or otherwise). Since you are not using GDM I think ConsoleKit is not the 
problem.
In fact, if things don't work without the patches (yours or mine), it won't work with them.

Without actually getting tinycorelinux myself and retracing your efforts, my best guess is that you are 
probably
correct in thinking that you forgot a dependency or built something against an incorrect one.
The only thing that comes to mind is gobject-introspection, dbus and udev (in that order).

Also, while I don't think your wrapper script is suspect, in Gentoo/Funtoo, we use the following .xinitrc:

# Fix Missing Applications in Gnome
export XDG_MENU_PREFIX=gnome-

# Properly Launch the Desired X Session
exec ck-launch-session gnome-session


Thanks - I'm using gobject-introspection-1.44.0, dbus-1.18.6 and udev-174 - udev is in the tinycorelinux 
base, so I cannot change that.

I'm reasonably sure I haven't missed compiling against gobject-introspection and/or dbus - what makes you 
think that I might have?

As mentioned, the only app that complains about udev-174 is gnome-bluetooth, so I haven't compiled against 
that.

I was thinking it was more likely that I'd missed a runtime dep, but what?
