Very slow start on mac desktop

[robbitybob]

Help please.  Loaded 3.2 on iMac and runs very well but start up is very slow as can be seen from output of analyze blame is:
        13.568s dev-mapper-linux\x2d\x2dvg\x2droot.device
          9.077s NetworkManager-wait-online.service
          6.414s ufw.service
          6.113s NetworkManager.service
          5.583s networking.service
          4.880s console-kit-log-system-start.service
          4.668s systemd-udevd.service
          4.517s lvm2-monitor.service
          4.319s thermald.service
          4.305s accounts-daemon.service
          4.167s ModemManager.service
          3.820s apparmor.service
          3.803s lightdm.service

          1.954s systemd-journald.service
          1.710s systemd-modules-load.service

Attached is system report.  I've used LL for years but only a basic "copy and paste" instructions user!  Any help appreciated.

Hello robbitybob,

Are you sure that you need all these services on boot?
ModemManager or samba-ad-dc , for example?

Please see following links and check if this can help you to improve your boot up.

• LL 3.0 - cleaning-your-linux-startup-process
  
• ubuntu speed up

Consider using a static ip address. This should speed up boot time - https://www.linuxliteos.com/manual/network.html

[Hanzo]

Consider using a static ip address

Requires to reconfigure home router. At least to check DHCP dynamic IP range.

Hi Hazno,

You don't necessarily need to reconfigure your Home router to assign a static IP address to your machine, unless the DHCP server in the router has specific rules in place to prevent it (unlikely in a home router DHCP server service). In regards to the DHCP scope, you can simply use the same IP that has been assigned to your machine by DHCP; that IP is already in the lease scope.

From Terminal:

Code:

ifconfig | grep 'Bcast'

The response should give you something similar to:

inet addr:192.168.1.122  Bcast:192.168.1.255  Mask:255.255.255.0

inet addr:192.168.1.122 is the IP address assigned by DHCP. Use it as the static IP for your machine when following Jerry's recommendation.

Jerry and Hanzo, apologies for not responding sooner - Christmas and 7 grandkids to blame!
Thanks for the suggestions which I've done but no real difference with time from switch on to using desktop about 90 seconds .  Is there anything else that can be looked at? 

[Hanzo]

Nothing I can think about without trying it.
Sorry.

It may pay to check the health of your hard drive. The start up times are slow across the board so providing you don't have any other hardware issues, I would check the health of your hard drive if I were you as your next step. Start here - http://superuser.com/questions/171195/ho...hard-drive and feel free to google other suggestions.

Also to add to what Jerry mentioned.

Maybe the bootinfo script will tell you what is hanging up on your boot process.
One can only try and see.

Jerry, thanks for those ideas I'll give them a try and let you know.  Cheers.
