[SOLVED] arch won't start after nvidia update, error : no screen found

Hello guys !
That's my first time asking for help so I'll try my best.

Ok so here's what I've done :
everything was going well on my computer. Wanted to execute some code on my GPU so i followed some tutorial, updating nvidia and nvidia-utils as well as installing cuda and cudnn. I rebooted my computer, and it's stuck before reaching the display manager. I've spent couples hours with friends (better than me in the arch's world) trying to figure out  what is going on, without success. what we have done so far :
* Start under windows (it's a dual boot) : no problem, so it's not the hardware
* tried to move away /etc/X11/xorg.conf, reboot, nothing change
* uninstall (using yay -Rs) nvidia, nvidia-utils, cuda and cudnn and then install back again nvidia, nvidia-utils and then use NVIDIA#Automatic configuration, nothing again
* went on NVIDIA/Troubleshooting page, tried :
** NVIDIA/Troubleshooting#System will not boot after driver was installed which looks like my error : I added nomodeset and nouveau.nomodeset=0 to the kernel parameters. Got a few new lines when boot up :

[FAILED] Failed to start Simple Desktop Display Manager.
See 'systemctl status sddm.service' for details
[    0K   ] Started Network Manager Wait Online
[    0K   ] Reached target Network is online
              Starting Docker application container engine ...
              Starting system logger daemon "default" instance ...
[    0K   ] Started system logger daemon "default" instance
[    0K   ] started docker application container engine
[    0K   ] Reached target multi-user system
[    0K   ] Reached target graphical interface

and then stuck again. As it didn't work, I didn't push to make this change permanent
** NVIDIA/Troubleshooting#Black screen on systems with VIA integrated GPU (following some advice on a topic, can't remember the link)
** NVIDIA/Troubleshooting#X fails with "no screens found" when using Multiple GPUs (following same advice)
* modified my /etc/X11/xorg.conf and created /etc/X11/xorg.conf.d/10-nvidia.conf (see below)
* and finally replace nvidia and nvidia-utils by nvidia-beta and nvidia-utils-beta

lspci | grep -E "VGA|3D"
08:00.0 VGA compatible controller: NVIDIA Corporation GP104 [GeForce GTX 1070] (rev a1)

/etc/X11/xorg.conf : http://ix.io/2inB
/etc/X11/xorg.conf.d/10-nvidia.conf : http://ix.io/2inA
/var/log/Xorg.0.log : http://ix.io/2inz
.xinitrc : http://ix/io/2iny

Thank you for your time and support

Post your /var/log/pacman.log as well.

Your kernel and FWIW your xorg is immensely outdated . Which leads me to believe you've installed these nvidia packages with the equivalent of

pacman -Sy nvidia

which you mustn't do, partial upgrades are not supported

Run a complete system update (and read the front page, there are a few packages within that time frame where you might've to manually interact with the update process).

That said, it's a good support request clearly showing what was tried and providing most logs of relevance, so you're off to a good start on that front.
