Why does the xinit package have many dependencies? How not to install unnecessary?

Question

linux

Good afternoon!

Raspberry Pi OS Lite installed on RPi 4 (no desktop). I want to deliver the simplest window manager (I3) and, accordingly, the X server. To run a program in kiosk mode that requires an X server.
Everything worked for me with the command sudo apt install xserver-xorg xinit i3
Here is its result:

I suspect that I don't need libraries at all

libwacom-bin libwacom-common libwacom2 libwayland-client0 libwayland-server0 xserver-xorg-video-amdgpu xserver-xorg-video-ati

How to put at a minimum what you need, without the left libraries?

Answer 1

sudo apt install xinit --no-install-recommends - won't pull recommended packages.
sudo apt install xinit --no-install-recommends --no-install-suggests - will not drag almost anything with it at all :) (except, of course, without which xinit will not work)
In general, if I had a Pi, then most likely, I would look towards remote control (X11vnc for example) - it APPEARS (but this is not accurate) nothing is needed except xserver-xorg, x11vnc and some kind of i3 environment, so that everything is beautiful and managed locally networks.

Answer 2

You can download the required deb package with apt, and install it using dpkg:
dpkp -i <путь к пакету>
dpkg does NOT install dependencies, only the package that was specified to it
