Comment 9 for bug 1187005

I've just found this entry in pm-utils' changelog:

pm-utils (1.4.1-9git1) raring; urgency=low

  Upload current Debian packaging git head.

  * debian/rules: Stop installing sleep.d/55NetworkManager. Current
    NetworkManager does not even expose this API any more, so the
    sleep()/wake() calls just always fail. As NM is apparently able to deal
    with suspends just fine, no need to waste cycles on this.

I guess that systemd-logind sends the "sleep" signal to network-manager, but network-manager never sends back the "wake" signal. So, the solution would be to just stop sending the "sleep" signal to network-manager on suspend.

PS: Am I talking to myself ? :)
