SDDM fails after hibernation freeze-up; hangs with "nomodeset=1"

This is a strange problem that I'm not sure where to start fixing.

My computer goes to sleep after ~10 minutes. Usually everything works well. This time, it went to sleep and would no wake up, forcing me to perform a hard-reset. Now, everything boots into a black screen—no cursor or anything. If I set nomodeset=1 in the kernel parameters, it hangs on "Starting default target..." and doesn't get anywhere (though I'm able to move to another tty). For the most part, starting with "Linux linux (fallback initramfs)" works (there are a number of bugs and oddities, but I can access the windows manager and SDDM starts).

Here are some journalctl logs that I got after setting nomodeset=1 and moving to another tty: https://pastebin.com/S9tVUttB

SDDM segfaults, but my guess is that this is a symptom of something else.

You are not expected to be able to get a display up with nomodeset. Disregard any notion of using that for getting a graphical interface running. What I do immediately see is a i915 option remove that.

If you can not boot without nomodeset and you cannot switch TTYs, reboot with nomodeset after such a situation  and post a

sudo journalctl -b-1

to get the log of the actually failing boot. 

If the fallback image works, then rebuild your initramfs with

sudo mkinitcpio -p linux
