If you are using kernel 6.6 or higher add the kernel parameter nvidia_drm.modeset=1 and initcall_blacklist=simpledrm_platform_driver_init otherwise xorg does not start giving segmentation fault
Here it's very simple, just run makepkg -si in all folders
It is also necessary to downgrade the xf86-input-libinput package in version 1.1.0 otherwise the keyboard and mouse did not work you can download here:
https://archive.archlinux.org/packages/x/xf86-input-libinput/xf86-input-libinput-1.1.0-1-x86_64.pkg.tar.zst
Uncomment the IgnorePkg line in the /etc/pacman.conf file and add xf86-input-libinput
like this IgnorePkg = xf86-input-libinput
you can do this also using this command
sudo sed -i 's/#IgnorePkg =/IgnorePkg = xf86-input-libinput/g' /etc/pacman.conf
