“Network management disabled” after suspend to ram kubuntu 10.04

solutions:
as said here

https://bugs.launchpad.net/ubuntu/+bug/555571

sudo service network-manager stop

sudo mv /var/lib/NetworkManager/NetworkManager.state /var/lib/NetworkManager/NetworkManager.moved

sudo service network-manager start

you could not again on the sysbar knetwork manager so you can try loading it

knetworkmanger

another solution could be this one

kdesudo kate /var/lib/NetworkManager/NetworkManager.state

now put everything true

[main]
NetworkingEnabled=true
WirelessEnabled=true
WWANEnabled=true

so now restarting network manager in another way like this

sudo service network-manager restart
