How can I reduce shutdown time?
The guest session takes only 1 second, but my session take about 10 seconds. I checked the first answer here, but apport doesn't show any thing is their any way to know where is the problem?
At the beginning it takes 2 seconds, after installing TLP it takes about 10 seconds but I think it's not caused by TLP because I installed it before on ubuntu 14.04 with no problems. Now I'm using 16.04.
