Painfully slow startup loading time

More than 40second of loading time and i would like to know if i can do something about it, i’m currently using manjaro 20.1, kernel 5.8.18, KDE plasma 5.20

I’ve a 8 core Intel i7 4770 (3.40GHz) and 16 gb of ram;

systemd-analyze print out this:

Startup finished in 2.131s (kernel) + 23.037s (userspace) = 25.168s reached after 16.524s in userspace

You can disable ModemManager.service by entering in a terminal: sudo systemctl disable ModemManager.service !

May I ask for the output of udevadm info --attribute-walk -n /dev/sda1 | grep 'DRIVERS=="[^"]' , please?

To you kind stranger:

$ udevadm info --attribute-walk -n /dev/sda1 | grep ‘DRIVERS=="[^"]’

Sweet! Thank you!
May now enter the following in a terminal:

sudo nano /etc/mkinitcpio.conf

Then find the line starting with MODULES=( and remove everything in between the parentheses, then add ahci sd_mod ext4 in between.

Next, find the line starting with BINARIES=( and once again, remove everything in between the parentheses. Thus, you can also add fsck fsck.ext4 if you prefer to quickly check the disk at startup.

Lets move on to the line starting with HOOKS=( , and remove everything, then add base autodetect .

After that, move completely to the bottom, and add


Hit ctrl+s then ctrl+x

You may now execute sudo mkinitcpio -P && sudo update-grub !

Reboot and voilà! :smile:

I was genuinely believing that i was about to destroy my installation lol

We at least got rid of 2 and a half seconds ! :partying_face:

I’ve leaved two hooks in place, now i try to get rid of them

Ah no, i did it at the end. Is already pretty good to me. Thanks, pretty good job

Is your PC a laptop, may I ask?
May I also ask if you use snap packages?

I don’t use it and i will disable it. My computer is a desktop

May execute sudo systemctl disable tlp snapd !

We can still go lower, but things becomes very complicated…

I think this is the best we may achieve!

Have a wonderful day!!

Thank you, next check i might consider to buy a couple of ssds after more than 4 years without upgrading my pc
