I recently installed Ubuntu 17.04 on my laptop that has 4 GB RAM, 1 TB Disk space, and 64 bit processor. To my horror, it takes about three and half hours to boot-up. I ran the following commands with their corresponding outputs below.
Output of systemd-blame
Startup finished in 8.860s (firmware) + 4.572s (loader) + 5.593s (kernel) + 3h 34min 27.734s (userspace) = 3h 34min 46.761s
Output of systemd-blame analyze
So, the two processes that are causing this traumatizing slow boot-up times are
- apparmor.service, and
- plymouth-read-write.service
I couldn't find anything comprehensible about these two processes to indicate their importance during start-up. Can anyone provide some insights and help me speed up the bootup time through either disabling them or suggesting a way around?
