Slow Userspace Startup

[djunna]

For the past couple months I've had an unusually slow startup time. Windows is actually faster for me right now. I'm a little out of my depth on this.
The results of my systemd-analyze are as follows:

tartup finished in 13.544s (firmware) + 13.901s (loader) + 4.031s (kernel) + 59.183s (userspace) = 1min 30.661s 
graphical.target reached after 47.670s in userspace

A list of my snaps:

I'm running Ubuntu 20.04.6. CPU is Intel i5-4430 and GPU is NVIDIA GeForce GTX 1060 (I know these are a bit old, but I am skeptical that it's a hardware issue given how well Windows 10 is running.)

Apologies for any ignorance of this forum's etiqutte.

You can dig a little deeper into the analyze output by running with blame and/or critical-chain

systemd-analyze blame
systemd-analyze critical-chain

I use Kubuntu which is a bit more lightweight that standard Ubuntu.
And do not install any snaps. And bit older system, that had early M.2 support now has NVMe type SSD. Not really noticeably faster than previous M.2 SSD, but main issue for slow system is between keyboard & chair.

fred@Z170-jammy:~$ systemd-analyze
Startup finished in 4.150s (kernel) + 5.574s (userspace) = 9.724s
graphical.target reached after 5.529s in userspace

Some settings to review, I started changes with 20.04, in 22.04 and still using changes in 24.04 test install:

Thanks oldfred! I applied the systemctl disables on must of them, and shocking how much seconds were removed. I'm guessing most are started after the desktop is up. It doesn't feel as though I'm gaining several seconds, as my desktop appears almost instantly anyway with nvme's that I have.
