Welcome to the forum. Please edit your post and use [ code ] tags (not quote tags) when posting output. This makes the output easier to read and provides a scroll box for long output.

Re: [SOLVED] Lightdm stop start - Wayland and Nvidia not workinng

Also please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Whatever the "/etc/default/grub" was supposed to be, it's hopefully not that file and seems to be part of the journal of an archinstall iso boot?
In case you're booting that and trying to start anything or posting information from there: DON'T.
Boot the multi-user.target (2nd link below) and post the journal from there.

Re: [SOLVED] Lightdm stop start - Wayland and Nvidia not workinng

Step #1: you've systemd-networkd, iwd and NetworkManager enabled, pick one network daemon and disable the others (you can use iwd as NM backend or all by itself, but you have to get dowsn to one daemon)

nvidia loads fine and early, so it's not a kernel issue
Step #2

[    13.952] (**) |-->Screen "Screen0" (0)
[    13.952] (**) |   |-->Monitor "Monitor0"
[    13.952] (**) |   |-->Device "Card0"

grep -r Screen /{etc,usr/share}/X11/xorg.conf*

I'm find the configs file in /etc/X11/xorg.conf.d/ block xstart. I'm delete and lightdm work like new.
