Re: Network Manager power drain

      Thanks to 'fedora' for replying,

        I am not sure how to make the threads work when I see this list
    in batched mode. His reply is here:

    |Do you need exactly NetworkManager? If you only have static connections 
|you may use network.service instead of NetworkManager.service
|
|systemctl stop NetworkManager
|systemctl start network
|systemctl enable network
|systemctl disable NetworkManager
|

    Alas this does not work. Start network fails. It seems
    NetworkManager is not

    the problem, the bridge probably is. 

    brctl show says:

    bridge name    bridge id        STP enabled    interfaces

    virbr0        8000.000000000000    yes        

    
    There was a nic-virbr0 interface, but some googling said it should
    not be there,

    so I deleted it and see no change. So I still see powertop reporting

    
      22.5 W      0.0 pkts/s                Device         nic:virbr0

    
    which seems unreasonable for a small device

    However, now I realsie bumblebee is not working, so maybe the nvidia
    card

    is the real culprit..I'll look there..

       Thanks,

       Bill

        Dear FC20 users,

             I tried posting a few days ago as 'Help

        with fc20 NIC power?  ' but had 

        no luck. My battery life dropped to about 20 mins with FC20. I
        THINK it is because

        NetworkManager is doing something bad with the virtual bridge.
        Certainly that

        is using all the power. But that does not show up in the
        'Network' box in gnome.

        So I am not sure how to fix it.

           Any ideas?

            Thanks,

               Bill
