Keyboard/touchpad not working on login screen

I did a full system upgrade with pacman -Syu, then rebooted. Now, the following occurs:

When booting the computer, it reaches the login/lock screen (SSDM) and the keyboard, trackpad, and trackpoint do not work. Additionally, plugging in USB keyboards/mice doesn’t work either.

The keyboard works in the BIOS and in GRUB. I can login via tty by appending 3 to the linux command in the boot parameters (note that using Ctrl + Alt + F2 does not work from the login screen). I’ve tried changing the kernel (5.10, 5.13, and 5.17 all do not fix the issue).

System information

I’ve removed some of the lines here that are (likely) irrelevant since I had to type this by hand on a separate computer. I couldn’t get SMTP to work from the tty…please let me know if there is something missing that is actually necessary.

i noticed you mentioned 5.13 kernel, that kernel is no longer supported … try it also with 5.15 kernel
