I'm very new to Ubuntu.
My PC has had very slow boot and shut down times (for 2 days), I reduced the shut down time with this tutorial (https://sites.google.com/site/installationubuntu/home/ubuntu-16-4-lts/make-slow-shutdown-faster) but PC still has some latency problem.
systemd-analyze blame from the terminal shows:
2.015s [email protected]
I think there is a problem but I don't know how to fix it.
