Since today, whenever I try to shutdown the laptop I get messages saying
"waiting for net.wlan0 (XX) seconds"
Where X varies between 50 and 5.
And I got this message for every service that is stopped. The problem
looks similar to what's described here:
But I couldn't get a solution from that forum.
Today was the day I installed network manager, but I don't know if that
has something to do.
