Last night I tried putting my Ubuntu 10.04 into hibernation. When that failed (apparently my system doesn’t support it) I was left with a machine in limbo, so the power button was all that could save me. This morning I turned the machine on to find no network connectivity, “Network manager disabled” was the friendly greeting – with no apparent way to enable it.
sudo service network-manager stop
sudo rm /var/lib/NetworkManager/NetworkManager.state
sudo service network-manager start
There are posts in forums all over the place about this. It seems silly behaviour, why not just restart it on boot?
Linux desktop managers have come a long way in their time, but it’s behaviour like this that sets them back just as far.
