Arch wont boot after installing nvidia package

Hello all,

Im trying to get a desktop on my first arch install and having a bit of issues. I was using lightdm, I3 and kde plasma all togther to have a nice desktop. (This is my Thinkpad T440p)
As some elements in kde needed graphics for things like transparency i figured i should install the nvidia drivers.
after installing and rebooting lightdm didnt work as intended, I could login but it was just a black screen. I tried to do some googling and changed some stuff based off of other arch forum posts.
But now I cant even get lightdm to start properly.
I created

\#!/bin/sh
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

to

/etc/lightdm/display_setup.sh

and followed the steps in here but I just get a flashing loop of

[   OK   ] Starting Light Display Manager
[   OK   ] Stopped Light Display manager

Right now im arch-chrooted into my system as ctrl+alt+f2 dosent work.

Any ideas on how to solve this?

Re: Arch wont boot after installing nvidia package

If you change the systemd boot target to multi-user.target on the kernel command line can you then access the system?
Edit:
If so then please post the journal for a boot with the issue.
If not then chroot in from the live media and post the journal for a boot with the issue.

See the tip box from pastebin to post command outputs from the console.

I changed to multi-user.target and it brought up the normal command line.
How would I get the journal for the boot?

Edit:
Would this be the correct command?

journalctl -b

Re: Arch wont boot after installing nvidia package

Journal#Filtering_output
The journal for the last boot would be:

journalctl -b -1

Ah ok, I ran that one instead of the just -b
Here is the output

This is what I have inside of my display_setup.sh file

#!/bin/sh
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

Re: Arch wont boot after installing nvidia package

When you followed NVIDIA_Optimus#Use_NVIDIA_graphics_only did you forget to install xorg-xrandr?

whoops I did not, I installed the package and set the boot target back to graphical and was greeted with the lightdm login screen.
But I noticed I did not have an /etc/X11/xorg.conf file and when I created one and put in the information and my graphics cards pci address startup errors out. Should I be skipping that step?
Upon logging in graphics certainly look crisper but I still cant enable transparency within KDE's konsole.

Please post the contents of /etc/X11/xorg.conf also the matching /var/log/Xorg.0.log

Re: Arch wont boot after installing nvidia package

I had deleted xorg.conf so I could use my machine but this is what I had in it.

 Section "Module"
    Load "modesetting"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:<2:0:0>"
    Option "AllowEmptyInitialConfiguration"
EndSection

Here is Xorg.0.log

Re: Arch wont boot after installing nvidia package

The xorg.0.log was from after  xorg.conf was removed.

    BusID "PCI:<2:0:0>"

the <> should not be included

    BusID "PCI:2:0:0"
