Why does the i3wm tile window manager start again before rebooting the system?

Question

linux

I start to reboot the system, all windows close, i3 also closes, the screen turns black and, in theory, the reboot itself should happen. But i3 suddenly starts up again (polybar panels and all this is loaded), then after a split second everything closes again, a black screen, and only after that a reboot occurs. Why is this happening? Has anyone experienced this? What could possibly be causing this?

Current i3wm config, just in case: https://pastebin.com/TNtQ5FRp

Answer 1

The problem was not related to i3wm...
Initially, I started the system without a display manager (DM). That is, at first the login and password were entered, and then xorg and i3wm were manually launched with the startx command. This suited me, but there was a problem with the TeamViewer program that did not start without a display manager https://community.teamviewer.com/t5/Linux/TeamView...
I did not want to install a graphical DM, so I chose nodm https:// wiki.archlinux.org/index.php/Nodm
It automatically started the session and solved the problem with starting the TeamViewer program. And it seems that he became the cause of the above described problem, because after removing it, the reboot began to work normally.
