Hi. I upgraded to Zorin Core 17 when the upgrade from 16 came available, and it's been mostly fine. The past week however, Gnome decided to take a minute or longer to start up after logging in (with the default login screen).
I've reinstalled my Nvidia-drivers, reinstalled zorin-os-desktop, removed all the config/cache files for Gnome I could find, and the reconfigured it to look alright again.
Still, Gnome takes a very long time to start up after logging in.
Is there anyone who could help me fix this?
After boot Have a look in terminal, with:
systemd-analyze blame
It will show what's slowing down your boot times.

I ran the command, and this is a list of the first 30 entries, ranked from big to small:
8.015s plymouth-quit-wait.service
6.967s NetworkManager-wait-online.service
2.297s postgresql@16-main.service
1.506s snapd.service
1.474s postfix@-.service
1.098s docker.service
1.066s gpu-manager.service
743ms fwupd.service
661ms mariadb.service
575ms nmbd.service
384ms dev-nvme1n1p4.device
334ms dev-loop1.device
334ms dev-loop3.device
334ms dev-loop0.device
334ms dev-loop2.device

333ms dev-loop23.device
332ms dev-loop24.device
332ms dev-loop14.device
332ms dev-loop17.device
Counting all the numbers together, it reported 38.895s
I've found online that the plymouth-quit-wait.service shouldn't be a problem, as it waits for the computer to boot while showing the splash-screen. I've disabled Postgresql as I don't need it for now.
yes, same for the NetworkManager-wait-online.service
the thing that's bothering me is all the dev-loop.devices.
Have you got a lot of snaps installed?

Not a lot no:

I'll disable NetworkManager as well
OK NetworkManager-wait-online.service should be fine.
Reboot and test again...
the dev-loop.devices are for each snap i believe.
Yes, that's what I meant, my apologies for the confusion. I'll reboot once inkscape is built

Hope its not a Snap 
Quick question:
Is it slow to boot - Or Gnome slow to load?
Gnome is slow to load. I think about 10-15s to get to the login-screen, then like a minute for getting to the desktop.
I agree, that sounds like Gnome, rather than boot.
The analyze-blame lists the overlapping times, not the total times, so adding them all up together is not going to be accurate since the reported times are non-sequential.
Can you please try reconfiguring GDM3?
sudo dpkg-reconfigure gdm3
I've rebooted with the above-mentioned services disabled, and with dpkg-reconfigure gdm3.
There was no difference, still had to wait a long time.
Btw, switching to tty3 and back to tty1 (with ctrl+alt+f1/3) doesn't help either.
Shutting down also takes remarkably longer then it used to, can that be from the same source as Gnome starting up slowly?
You can use journalctl -b to check your boot log. To see your last boots log, run
journalctl -b -1
journalctl -b -1 doesn't give the most recent ones, but the normal journalctl (without flags) does work:

Are you dual booting with Windows OS?
Yes I am (and actually even Arch on seperate SSD)
With Windows OS, ensure Fast Startup or Fast Boot is disabled in the Control Panel > Power options.
Also, please be sure to check that it fully shuts down before booting Zorin OS or Arch as windows will actually hibernate and retain control over the motherboard...
In terminal can you run
systemctl --user status xdg-desktop-portal.service
and look for how much time passes between starting... and started
Also:
Have you tested logging in on X11 desktop (Xorg) instead of Wayland? You might test this while repeating the command above giving numbers to compare against.
The problem now has solved itself, I don't really know what caused it =(
