Ive collected 3 workarounds, and they work differently. Maybe this would help developers. Also I have lan network printer.
1) suspend via " sudo pm-suspend " - the best option. LAN printer doesnt make a noise and doesnt reinitialise and network continues to work, there ar no notifications about reconnection 2) turn on the password dialog on the wake up. This makes my printer make a noise and networks works too 3)place wakeup script in /etc/pm/sleep.d/ . Printer again reconnects to the computer with noise. -- You received this bug notification because you are a member of DX Packages, which is subscribed to systemd-shim in Ubuntu. https://bugs.launchpad.net/bugs/1252121 Title: missing PrepareForSleep signal after resuming, causing networking to stay disabled Status in NetworkManager: New Status in wicd: New Status in “systemd-shim” package in Ubuntu: Confirmed Status in “systemd-shim” source package in Saucy: Confirmed Status in “systemd-shim” source package in Trusty: Confirmed Bug description: 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 MarkForUpload: True 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.
