I'm on fully up-to-date Ubuntu 14.04 with the latest kernel
3.13.0-36-generic, and I got this error. I have a Lenovo ThinkPad W530.
I use it either with the internal monitor or with an external monitor
connected to displayport. I don't remember what I did today. I think I
connected the display cable, closed the lid and then logged in. I do it
every day, but something must have been slightly different today.
I got "network disabled". I clicked on "Enable Networking" several
times, but it didn't help. There was no error message and no change in
the menus shown on left-click or right-click on the nm-applet.
This didn't work:
# service network-manager restart
stop: Unknown job: network-manager
start: Unknown job: network-manager
This worked:
# nmcli nm
RUNNING STATE WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN
running asleep enabled enabled enabled
enabled
# nmcli nm sleep false
nm-applet should show the sleep state and should wake up NetworkManager
if requested by the user.
Ideally, it would be great not to put the network to sleep if the
computer is not going to sleep. And the computer should not go to sleep
if the lid is being closed but there is a display connection.
