This suggests systemd for some reason is not on the bus. That's almost
certainly a bug. No idea how that can happen, there might be something
in the logs explaining why it disconnected from the bus.

Usually "systemctl daemon-reexec" should make systemd reconnect to the bus.

[systemd-devel] Strange problem: Failed to get properties: Failed to activate service

2018-10-17 Thread Cecil Westerhof
Since this morning I have a strange problem, when I execute:
systemctl status cups

I get:
Failed to get properties: Failed to activate service
'org.freedesktop.systemd1': timed out

This is with every service, not just cups.

I tried 'everything', even rebooting the system.
What could be the problem.
This is with:
systemd 239
+PAM +AUDIT +SELINUX +IMA +APPARMOR +SMACK +SYSVINIT +UTMP
+LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ +LZ4 +SECCOMP +BLKID +ELFUTILS
+KMOD -IDN2 +IDN -PCRE2 default-hierarchy=hybrid

On:
Distributor ID: Debian
Description:Debian GNU/Linux 9.5 (stretch)
Release:9.5
Codename:   stretch

Re: [systemd-devel] systemd suspending docked laptop?

Use "systemctl edit systemd-logind", then enter this into the editor
that opens:


[Service]
Environment=SYSTEMD_LOG_LEVEL=debug


Then issue "systemctl restart systemd-logind".

This will turn on debug logging for logind, that should tell you
exactly what it is doing any why.

If you need help with the gdbus API I'd recommend pinging the glib
mailing lists, they are the most likely to help you with that. gdbus
is not directly related to systemd, we can't really help you here.

Hope this makes sense,

[systemd-devel] logind + GDbus API

2018-10-17 Thread Germano Massullo
Good day, I planned to write a tiny software for testing purposes that
will use GDbus API to interact with logind, in order to detect user
idle time.
I am still studying GDbus API, and I am also looking for some very
good example of GDbus API + logind usage, in order to learn best
practices in using both of them.
Do you know any? I actually have not found anything yet that fits my
needs, but there should be some for sure. I have just found this
StackOverflow topic [1]

Thank you for your time
