Display Manager broken after update

I use KDE with SDDM and after a recent update my computer won't display a login screen and I can't startx from tty2. I can however login from tty2. Is there a way to copy and paste my journalctl to a USB or something? As for SDDM, here is what my systemctl status sddm.service says:

sddm.service - Simple Desktop Display Manager
Loaded: loaded (/use/lib/systemd/system/sddm.service; enabled; vendor preset: disabled)

I also tried switching to lightdm and the lts kernel, but neither worked.

You can post the journal from the console with the instructions from List_of_applications#Pastebin_clients.

I suggest you add the Xorg log to the journal.

I don't know what happened or why, but SDDM appears to be working again. I can login, use the desktop, etc. I'll post my logs just in case.

That looks like the session journal (which doesn't help here, run "sudo journalctl -b" instead) and the xorg log says that you've an optimus system and created an Xorg.conf w/ nvidia-settings (what's not a very good idea and often causes problems) - please read up https://wiki.archlinux.org/index.php/Optimus and linked articles.
