(Nvidia) After recent updates, can't start X or a DM (FIX: downgrade)

Both SDDM and GDM just give me a black screen. I tried deleting xorg.conf, recreating it with nvidia-xconfig (didn't work), deleting that and replacing it with a "minimal" one from the wiki (didn't work)...

I keep getting "no screens found" errors from X, and I went through the journal for sddm but nothing stands out. What should I do?

EDIT: Downgrade nvidia, nvidia-utils, and nvidia-libgl as detailed in the posts below.

EDIT2: There should no longer be a need to downgrade.

I don't know if it's related but i had a problem where a symlink wasn't being created and i was getting an error cannot start kde error while loading shared libraries: libEGL.so.1 cannot open sharred object  file: no such directory. ln-s /usr/lib/mesa/libEGL.so.1 /usr/lib seemed to fix that problem for me. Had to add the symlink for the 32bit library as well to get steam running.

Re: (Nvidia) After recent updates, can't start X or a DM (FIX: downgrade)

I was able to start X after downgrading to the previous version of the NVIDIA driver (375.26):

nvidia-utils: https://archive.archlinux.org/packages/ … pkg.tar.xz
nvidia-settings: https://archive.archlinux.org/packages/ … pkg.tar.xz
lib32-nvidia-utils: https://archive.archlinux.org/packages/ … pkg.tar.xz

For DKMS users: https://archive.archlinux.org/packages/ … pkg.tar.xz
For stock kernel users: https://archive.archlinux.org/packages/ … pkg.tar.xz
For stock LTS kernel users: https://archive.archlinux.org/packages/ … pkg.tar.xz

However, nvidia-libgl conflicts with nvidia-utils, so the only available libGL provider is mesa which gives horrible performance. If anybody knows a way to install both nvidia-utils and nvidia-libgl, please share your knowledge. Here they are:
nvidia-libgl: https://archive.archlinux.org/packages/ … pkg.tar.xz
lib32-nvidia-libgl: https://archive.archlinux.org/packages/ … pkg.tar.xz

I had to use the nvidia-utils and nvidia-libgl from December 16th in order to downgrade the nvidia packages

Thanks for the help guys, it's fixed now. I went to the archive, grabbed the older packages and set pacman to ignore them for now. I wonder what was changed, and how many people it affected?

Well, I got the kernel/firmware update released today, which didn't work with the older Nvidia packages I was using. So I updated them, and now they work fine.
