As the title says, I updated glibc to 2.23-5 on 13th June. After booting into Arch, it simply presents me a black screen. I used Alt + Ctrl + F2 to access a different tty, tty2, and used
journalctl -bto find out that SDDM has segfaulted.
Taking a look at /var/log/Xorg.0.log told me that it could not find a device to connect to.
I recompiled glibc following the instructions in this post, and it still did not work.
Using nvidia-xconfig, or Xorg :0 -configure did not help either.
In the end, I just removed the xorg.conf file, and rebooted, which worked.
Any help would be appreciated!

The output of `lspci -v | grep VGA` lists two cards typical of a hybrid graphics setup.
From the Screen section of both xorg.conf you have generated these instruct xorg that the display is connected directly the the nvidia card rather than routed through the integrated card which is typical of a hybrid setup.
If this was an issue with the upgrade to glibc to 2.23-5 then reverting to the previous should have resolved it ( without the need to change xorg.conf )

So, I assume that there were no problems prior to the update? For how long?
Were other changes made at the same time?
Was the update accomplished via pacman or locally compiled? Was this a single package update or a system-wide update?
What's the output of "$ pacman -Qs nvidia"?

Can confirm the segfaults after upgrading glibc to 2.23-5.
I resolved it temporarily by downgrading to 2.23-4.

There were no problems with the system, which I'd first installed a month ago. This was my first foray with Arch, and I'd installed with nvidia drivers. After the aforementioned update to 2.23-5, these problems started. Prior to these problems, I had not modified the stock xorg.conf. At the same time, nvidia-utils, nvidia, and lib32-nvidia-utils alos underwent an upgrade alongside gcc, systemd etc. These were all updated using pacman, using:
pacman -SyuAs of right now, I've used a workaround by using Bumblebee, which starts my X session using the intel drivers, and does its thing. So I do not know how useful the output of the following commands will be to you.
$ sudo pacman -Qs nvidia

I resolved it temporarily by downgrading to 2.23-4.
Could you please tell me how to accomplish the downgrade to 2.23-4? I am a bit apprehensive of downgrading an important package such as glibc without verification.

This and the other info I requested provide a better picture of the environment and factors that may point toward a resolution. My experiences and observations have shown that many NVIDIA problems begin with driver dependencies and conflicts.
In the FWIW Dept, did you re-image initramfs after the upgrade?

@buchno is your system a hybrid graphics system like dipack95 also were you using sddm like dipack95.
Here using lightdm none hybrid graphics glibc 2.23-5 nvidia 367.27-1 no issues.

By re-imaging the initramfs, do you mean running the mkinitcpio command? If so, I did not. I did not do anything explicit, after the pacman upgrade completed.

Here is the appropriate backtrace from gdb, for the sddm crash.

Yes. I've found that after a systemd upgrade, a manual initramfs re-imaging (regeneration) was required. Yes, mkinitcpio.

The yaourt failure would seem to indicate it is not connected to Nvidia or the X server.
Only suggestion I would make other than considering filing a bug report would be Microcode update
