I'm new to Lubuntu and Linux in general.

I've tried to revive an old Dell D630 laptop by installing Ubuntu 18.04 x64.

I have solved a few problems, but I'm still suffering with very slow boot times and slow resume from suspend. The device has an SSD so I don't think it should be taking several minutes to boot as it is doing currently. 

$ systemd-analyze

What could be the issue here and how can I fix it?

  • This Lubuntu x64 is installed on SSD. The truth is that: 1): windows 7 is booting on the same drive in 20 seconds. 2) Lubuntu x86 on very old Toshiba L20 ssd is booting in 30 seconds with no black screens. So I think that something is going wrong - how to find out what is wrong? – alex Sep 21 '18 at 17:38
  • I have to apologize, because the initial comment was intended for another question. Anyway, the first four lines are probably the cause. I am not entirely clear what is booting when and why, but that's probably irrelevant, as long as Windows and Ubuntu don't boot at the same time. – mikewhatever Sep 21 '18 at 22:33

As proposed in Slow boot times since 18.04 installation on Dell D630

I changed the GRUB_CMDLINE_LINUX_DEFAULT line in /etc/default/grub to: 

GRUB_CMDLINE_LINUX_DEFAULT="video=SVIDEO-1:d"

And ran sudo update-grub.

Now my boot time is about 30 sec:

$ systemd-analyze
Startup finished in 5.053s (kernel) + 32.055s (userspace) = 37.108s
graphical.target reached after 32.038s in userspace
