[SOLVED] Black screen at login/Corrupted GPG keys (packages in post)

Hi everyone,

My issue is resolved, but I wanted to report it here because it is related to some package upgrades I had today, and one from 9/10/2026.

The issue I was experiencing was that when I would try to boot, after getting to the LUKS password, it would go black screen before loading PLM and prompting for my login password. It was hard frozen. I couldn't even get a TTY with Ctrl+Alt+F2/3/4.

After various troubleshooting, I was able to determine the issues were with the following packages:

libldap 2.7.1-1
linux-firmware-amdgpu-20260910-1

My system has a Ryzen 9 7900X and a Radeon 7900XTX.

The solution was to downgrade both packages and lib32-libldap to the previous versions. This solved the display probe issues and I was able to successfully complete the boot process from GRUB to Plasma.

Which leads me to my next issue.

This relates to corrupted GPG keys.

The problem package:

libgcrypt 1.12.4-1

When booting into Plasma I am greeted with a message of "gpg: keydb_search_first failed: Invalid argument"

gpg --list-keys returns the same error.

The solution was to again downgrade libgcrypt to 1.12.3-1 and then I had to delete my ~/.gnupg directory and regenerate.

I had my gpg keys backed up so I was able to import them after the downgrade and regeneration.

I just wanted to share this as I am sure others may experience a similar issue.

Similar issue here. Upgraded to linux-firmware-amdgpu-20260910-1 and had the same black screen issue during initrd right after LUKS prompt.

My system is AMD Ryzen 7 6850U with integrated graphics.

Steps to fix the issue:
- Reboot and press 'e' on grub to edit
- Add `nomodeset` kernel parameter at the 'linux' line
- Boot into arch
- Downgrade linux-firmware-amdgpu to anything before 20260910. I downgraded to 20260810-2 and had no issues booting afterward
- Reboot

However I experienced major screen tearing and lag. To fix it, I downgraded the following packages:
- linux-firmware (except linux-firmware-other. This had conflicting files with other linux-firmware packages so I kept it as is)
- mesa
- vulkan-radeon
- amd-ucode

Not sure if amd-ucode was necessary. But after this all lag was gone and my system was back to normal.

Hopefully this helps someone else.
