[arch-general] Complete mess after having attempted to install Nvidia drivers

Hello, I was trying to remove the proprietary drivers for my nvidia, to install the open source ones. I read in the wiki that I also had to remove the /etc/X11/xorg.conf, but only found an /etc/X11/xorg.conf.d, so I removed that one. I don't know if this is the reason why I can no longer use either the keyboard or the mouse when reaching the login screen. Let me add that I forgot to also remove the intel video drivers that I used before, don't know if this could have anything to do with what I'm facing now though. The question is, what did I do wrong and how can I fix this? I tried adding either 3 or 1 to the grub kernel line, but I still can't reach the command line.
