No video output on metal after grub boot

Bug Report

Stuck in boot after kern/efi/sb.c:111: UEFI Secure Boot state: Disabled is printed.

Description

Trying to boot into 1.6.1 or 1.4.4 version of Talos on a HP Elitedesk 705 G4 DM. Without set debug=all, the machine hangs with a black screen and an underscore. After enabling the debug option, the boot process hangs immediately after printing the above log line.

I have attempted the boot process with all drives removed and a single stick of ram to eliminate as many variables as possible and this happens with all 3 of the machines I have.

Only mention I can find of a similar issue anywhere:

Also want to note that trying to set set debug=all,-mmap does not seem to be working.

Ok, upon further work, it does seem that it is booting, but just nothing is coming out of either display port.

Usually it's related to the console= settings, you can try tweaking it, removing console=ttyS0, changing to console=tty1.

Unfortunately it's hardware dependent.

I closed this a bit early, I am thinking this might be something else as it seems to just reboot after about 5 minutes.

I have the exact same issue with my n100 board from asrock. I can boot any other Linux distribution like Ubuntu just fine.

[runningman84]

with talos 1.7.0 beta 0 that is the output.

[smira]

Try removing console=ttyS0 boot argument.

[runningman84]

Removing all console= parameters it boots just fine with version 1.6.7 and 1.7.0.beta.0. Are these settings persistent after the install? Why do all linux distros work out of the box but talos has issues like this?

[runningman84]

These settings get lost after the initial install so I have to modify the grub parameters for each boot. How can I persist that in talos?

[smira]

Console argument issue is a hard one, see https://www.talos.dev/v1.6/introduction/what-is-new/#kernel-arguments on how to remove default args.

Thanks that worked for me!
