Hi, everyone. I'm using ubuntu 12.04, but I have replaced Unity with Mate(a fork of gnome2) by unistalling and installing lots of softwares. Everything seems fine, except the Network-Manager applet on the top panel. It just displays:
OK, I run the code in terminal:
NetworkManager is not running.
, then I get the message:
sudo service network-manager start
Then I tried to restart:
start: Job is already running: network-manager.
All right, something seems changed,
sudo service network-manager restart.
But NetworkManager still cannot manage wireless and wired connections. It told me:
network-manager stop/waiting, network-manager start/running, process 8955.
But I'm sure that the network devices are running properly, for I am using wireless network to communicate with you! What's more, If I login Mate with root instead of normal user, I can use the NetworkManager-applet properly. Can anyone tell me what's the matter?
No network devices are available.
P.S. I cannot find the option or button to shutdown in normal user, but when I login by root, I can easily find the option in top menu to shutdown. Can anyone tell me how to add the shutdown option in normal user? What's the name of that shutdown software in top menu? Thanks a lot!
