[Bug 1252121] Re: missing PrepareForSleep signal after resuming, causing networking to stay disabled
Currently using Xubuntu 14.04.2 updated.
I have tried all the workarounds (restarting services, scripts, unload module files, etc) and none of them work for me.
The issue I experience is related only to wired connection (DSL or
Ethernet connections) and *not* with wi-fi.
What I found out and what is not mentioned often is that for me the
issue only happens when my laptop is on battery power (battery mode). If
the laptop is plugged into AC, no issues.
Network driver = r8169 (Realtek)
Note - wi-fi says disabled, because I disabled it myself. Unlike ethernet, I don't keep the wi-fi always on.
Are there any news about this bug ? Reading all the topics here and on Ubuntu forums, ASK Ubuntu, I see it is present for 2-3 years now ?
Thanks !

As per request from bug #1184262, this is a new report, along with
dbus (to be attached)
ProblemType: Bug
DistroRelease: Ubuntu 13.10
Package: systemd-services 204-0ubuntu19
Uname: Linux 3.12.0-custom x86_64
ApportVersion: 2.12.5-0ubuntu2.1
Architecture: amd64
Date: Sun Nov 17 20:24:41 2013

SourcePackage: systemd
UpgradeStatus: Upgraded to saucy on 2013-10-17 (31 days ago)
SRU INFORMATION:
FIX: https://github.com/desrt/systemd-shim/commit/9e1ebe3ab (in trusty already)
Regression potential: Low. Flushing the session bus was introduced in
version 4 and is obviously bogus as in a system D-BUS service there is
no session bus. This causes lots of confusing error messages and
unnecessary overhead like trying to start dbus-launch. Flushing the
system bus is low-risk, in most cases it's a no-op and it would
otherwise prevent losing signals after waking up. No known
regressions.
TEST CASE: Run several suspend/resume cycles with the lid, session
indicator menu, and verify that the network comes back up. It is known
that this fix is necessary but not sufficient, so it is not expected
to fix all cases. But it should not make things worse, so if network
now does not come up any more on a machine where it previously worked
this would count as failure/regression.
