GRUB prompt unable to recognize QMK keyboard even after disabling NKRO

I use a Keychron V5 ANSI keyboard and have done so during my installation of Arch. After following the installation guide, installing GRUB and attempting to boot into the new OS, I was met with a command prompt. But when I tried to type anything, there was no response at all. I discovered that boards with n-key rollover enabled tend to have this problem and followed this process to disable it:
- Went into the qmk_firmware directory and found the directory for my keyboard (my normal OS is Windows 11 FYI)
- Edited rules.mk, setting "NKRO_ENABLE" and "MOUSEKEY_ENABLE" to "no"
- Set "VIA_ENABLE" to "no"
- Checked that "FORCE_NKRO" wasn't defined
- Created a new keymap folder
- Technically unrelated but I set the numpad + key to space
- Compiled it in QMK MSYS
- Flashed it in QMK Toolbox
And then I returned to GRUB, but again, no input was detected. Could it be another issue? Feel free to request any other information.

Re: GRUB prompt unable to recognize QMK keyboard even after disabling NKRO

I followed the instructions presented in this article: https://www.elevenforum.com/t/turn-on-o … s-11.1212/
Even after doing so and shutting down afterward, I booted back into GRUB and still, nothing happened when I attempted to type. Also, doing "(GP "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Power")."HiberbootEnabled"" returned 0 after I booted back into Windows, so I'm not sure what's happening.

Re: GRUB prompt unable to recognize QMK keyboard even after disabling NKRO

have you tested a regular ps/2 / usb 104 standard keyboard?
could be whatever you using is just too advanced and doesn't support a proper legacy mode
also: check your uefi if you have usb legacy enabled to make keyboards work at low level like bootloaders

tldr: looks like a hardware issue - or turned upside down: it's just not supported by the base drivers grub comes with

if you ever wondered why modern boards still come with ps/2 ports - not just for over clockers but also for such stuff

When I go into UEFI, there is no such USB Legacy option. My keyboard also did not come with a PS/2 port but I do have some slightly older keyboards that might work; otherwise, I don't have many options. I'm going to wait and see if someone might provide a better solution.
