System very slow to open

When I start the computer it seems to take an age to open . I ran “systemd-analyze blame” and the following are the screen shots . Is this what it runs before opening and if so can I get rid of some to make it faster .

Hi @bobel, We got no screenshot.

When capturing the screen, “Copy to Clipboard” and paste that as you would text. It works well.

Ok sorry about that . I do not have a clipboard but I copied it to 'writer' so will see if that makes a difference .

My system is:
Computer HP Compaq-dc7900
Memory 2Gb
HDD 150Gb
Processor Intel cor 2 duo CPU E8400@3Ghz
OS Ubuntu 16.04 Mate

Hello
I've been affected by this on 17.10.

Try the following:

sudo systemctl disable NetworkManager-wait-online.service

Thank you ouroumov . Done that but “dev mapper ubuntu” takes over 11 secs now . Is there any other that I can disable that will not affect the operation of the OS
