Josh, if this gets too long and you think it better for me to start an independent thread, please let me know.
AMD Ryzen 5 4650G (integrated graphics) - ASRock A520m-itz/ac board - After running
sudo eopkg up and rebooting:
Expected: Prompted for LUKS passphrase. It shows on a single screen as B&W, flickers, and then shows B&W on both screens.
Unexpected: Prompted for LUKS passphrase. It shows on single screen as B&W, flickers, and then I had a lovely green background on both screen and the text became very difficult to read. This carried on through to my desktop including flipping to TTY. Also happened with only one monitor connected.
I have full logs from dmesg and journalctl for both instances and can provide them if that would be helpful. Unfortunately, I don't know enough to pin down what might be the actual culprit. I did notice this error/line on the "green" log as one difference:
amdgpu 0000:08:00.0: amdgpu: Unsupported power profile mode 0 on RENOIR - According to this issue the "message is harmless".
Anyway, 5.10 still works fine, but you asked for feedback.
