/usr/lib/pm-utils/sleep.d/55NetworkManager calls the wrong method

[István Váradi]

As of 11.10, 55NetworkManager calls the already non-existing "sleep" and "wake" methods on org.freedesktop.NetworkManager. It should call instead the "Sleep" (note the capital 'S') method with a boolean argument:

dbus_send ... ... org.freedesktop.NetworkManager.Sleep boolean:true

for suspending, and false for resuming.

Attached the fixed file.

Status changed to 'Confirmed' because the bug affects multiple users.

Moreover, it's calling 'dbus_send' instead of 'dbus-send'.

[Sidnei da Silva (sidnei)]

Argh. And '--type=method_call' is missing too!

i just stumbled across this bug after filling a duplicate bug (#906347).

Calling dbus_send is perfectly correct, it is defined in $PM_FUNCTIONS as a wrapper to dbus-send.

The bug seems to be still present in version 1.4.1-9fix.ubuntu12.04

Is anyone able to fix this? Is it fixed in future versions?

[Oliver R. (oliverr)]

I attached a modified version of 55NetworkManager that simply calls "stop network-manager" and "start network-manager", respectively. This works for me, i.e. I have a working network connection after resume, which I hadn't before (Mint 13 Xfce, kernel 3.13.0-43-generic, ThinkPad R500).

Please comment if this is a sensible solution – or post a correct version using dbus_send.

This is not a sensible solution.

There are numerous patches already to fix the original problem:

There are also some random sources on the internet saying that NetworkManager also listen to UPower events.
