Slow boot after installing ubuntu 24.10

[trancos93]

Good morning,

Yesterday I successfully installed ubuntu 24,10 on my desktop PC to dual boot with windows 10,

The issue i'm experiencing is that it boots so slowly in comparison with windows 10. It doesnt make sense, taking into account it's a lighter OS,

I've ran some commands to check what was happening but i'm having some trouble interpreting them:

systemd-analyze critical-chain:

graphical.target @9.208s
└─power-profiles-daemon.service @9.155s +52ms
└─multi-user.target @9.154s

My system is pretty powerful so I dont understand this boot times,

Any help would be apreciated,

Thanks in advance.

I don't know if this is the reason for the difference but the default on windows 10 is hibernation on so it is not actually doing a full boot/reboot so it seems faster.

My laptop, this Dell with 11th gen Intel comes up about 10 sec after grub menu, but this says it sill is booting.

fred@m2-noble:~$ systemd-analyze
Startup finished in 11.975s (firmware) + 5.611s (loader) + 2.956s (kernel) + 9.717s (userspace) = 30.260s
graphical.target reached after 9.710s in userspace.

My desktop is similar, but I remove a few more settings as it does not have hardware for that.

I typically change some settings & remove all snaps.
My older desktop does not have UEFI update, so fwupdate not required. So I do vary settings a bit depending on which system.

I also turn off in UEFI settings network boot, so UEFI is not trying to connect to network.

Go back and look at the top two lines...

$ systemd-analyze critical-chain
The time when unit became active or started is printed after the "@" character.
The time the unit took to start is printed after the "+" character.
