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;

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

Howdy!
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?
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
COMPRESSION="cat"
Hit ctrl +s then ctrl +x
You may now execute sudo mkinitcpio -P && sudo update-grub
!
Reboot and voilà!

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

We can still go lower, but things becomes very complicated…
I think this is the best we may achieve!
Have a wonderful day!!
