Hello everyone,

after installing I was wondering how this can be that an OS boots within
some seconds?

From other distros I am used that boot needs around 20-40 seconds, but
Ubuntu 23.10, after passing the (legacy) BIOS, is prompting its graphics
surface after around 4-5 seconds.
This looks to me that they created some kind of image which is unpacked
and started when booting. It's just, that I do not remember that such
options were shown during installation.

Besides this, any change to files in the /etc/profile.d directory do not
take effect directly after modifying. Maybe, instead, remaking the image
afterwards is just triggered to make the changes permanent.

It seems that these two things are somehow related.

Does anyone know exactly what's behind that warpspeed boot?

Thanks!

best regards,

Markus

Most likely in the other situation a service stuck.

Disable the boot options "quiet" and "splash" in /etc/default/grub and
boot again or use systemd-analyze blame to find the stuff that takes
long.

Hi Paul, Marco,

it's normal boot, no sleep-mode or hibernate. Machine is a laptop /
notebook with docking station.

I just went into grub menu, now, selected "advanced options for Ubuntu"
==> "Ubuntu with Linux 6.5.0-10-generic". ==> It prompts

"Loading Linux 6.5.0-10-generic ...
Loading initial ramdisk ..."

After that, it says that /dev/sda1 is clean,
and a few seconds later, graphics mode is active.
No systemd messages like "xxx target reached", "waiting for service yyy"
and so on are displayed as known from other distros.
Same behaviour when just booting without touching anything but even
faster.

Best regards,

Markus

That was precisely the thing that sped up the boot on my desktop system
at some point, namely turning off the flood of text on the display
during boot with the "quiet" kernel option. It goes pretty slowly at
least with my Nvidia GPU.
