Slow boot (used to be faster)

[fynn-boeltau]

Hello all,
i somehow have the problem that Ubuntu 16.04 takes a longer time than it used to take to boot.

Here is my dmesg output: https://pastebin.com/BVum36Fh

Welcome to the forums, fynn-boeltau.

Have you changed your physical configuration? Did you disconnect or turn off Bluetooth?

Please post output of:

systemd-analyze blame

No i haven't, i have however changed the size of my windows dual boot partition, but i think that was after the slow boot occured.

According to this output, your boot isn't slow. Perhaps we should start with some definitions: what do you mean by slow. Please actually measure and quantify in seconds.

It now takes 1min 45sec from grub to login screen.
Used to be <30sec. I do have an SSD.
Best, Fynn.

Is the bluetooth plugged into a USB port, I would remove it for boot if possible

[fynn-boeltau]

I don't have an external bluetooth device, I will try to turn off Wifi/Bluetooth during boot now and report back in.

edit: makes it faster by ~2 sec.

Do a

sudo -H gedit /etc/default/grub

Find the line with "quiet splash" and change it to "quiet splash ipv6.disable=1"
Then in terminal

sudo update-grub

Reboot
