[SOLVED] Complete system freeze on lightdm login screen

Hello!
Quite randomly, the system may hang at the lightdm login screen. After that, the laptop does not respond to pressing any key combinations, for example: (ctrl + alt + 2,3,4, Caps Lock, etc). Only pressing the power button helps. I have already come to terms with the fact that I cannot use sddm or sddm-git, which also causes random freezes, as it turned out later. Please help me figure out the problem...

You've networkmanager and dhcpcd enabled, pick on, disable the other.

Only pressing the power button helps.

Wat means the log of the boot won't be preserved.

You seem to use an AMD/nvidia hybrid graphics system - please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General

That's not where lightdm stores the xorg log and the one you posted is from Thu May 18 13:24:18 2023

But back then you were running the modesetting driver on the nvidia ampere chip (and the novueau kernel module) what is rather not what you want - and if  the status quo, most likely the source of your problems.

Looks better, but doesn't explain your issues.
See whether you can preserve a log w/ the magic sysrq.

Alternatively, if you can, disable the AMD GPU and run on nvidia only.

You've networkmanager and dhcpcd enabled, pick on, disable the other.

After disabling dhcpcd:

$ sudo systemctl disable dhcpcd

The issue has been resolved and the system no longer freezes over a long period of time . Thank you!
