Enabling secure boot for your Arch installation is very easy now with the "sbctl" tool
EDIT: Actually, I tested this just now by setting module.sig_enforce=1 in the kernel cmdline and it doesn't work. It turns out Fedora/Ubuntu/etc ship this custom patch in the kernel that explicitly allows using platform (secure boot) keys for verifying kernel modules: https://gitlab.com/cki-project/kernel-ark/-/commit/07db43366d560153fd1d418cfebe2370fb20697e. The patch is not in the upstream kernel yet, so Arch doesn't have it.

This is the amount of time gnome waits before trying to determine if an application is not responding. At 5 seconds it almost immediately triggers for league of legends (and some other applications) if those applications are still in the loading phase. We feel 30 seconds is a much more reasonable wait time. gnome mutter patched with x11 fractional scaling: https://salsa.debian.org/gnome-team/mutter/-/raw/ubuntu/master/debian/patches/ubuntu/x11-Add-support-for-fractional-scaling-using-Randr.patch gnome mutter wayland and x11 fractional scaling enabled by default: https://wiki.archlinux.org/title/HiDPI#Fractional_scaling gnome shell patched with https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2358 to allow gnome-extension-manager to auto-update without needing gnome-extension-app installed.

This is why Valve is switching from Debian to Arch for Steam Deck's Linux OS
Do do indeed, but they also curate their own downstream patches for the kernel and system libs. Their kernel repo is here https://gitlab.com/cki-project/kernel-ark. You have to specifically opt in to vanilla mainline builds of the kernel via https://fedoraproject.org/wiki/Kernel_Vanilla_Repositories.

Show HN: SSH-tpm-agent – SSH agent for TPMs
No, this isn't true nor correct.
Secure Boot and TPM do offer tangible security benefits and is security features you can take ownership of.
Secure Boot allows your own key hierarchy, and TPM allows you to take ownership.
The linked boot disk isn't really proof that Secure Boot is useless. If you don't set a MOKManager password (as you should), and you change the security state of the machine while present at the keyboard. Yes you can boot things.
This is intended to make sure people can actually decide to trust things. And having insecure defaults makes this less useful. Not very surprising.
TPMs could also prevent attacks like this on your machine.
Incidentally I've invested quite a bit of time in making user-friendly Secure Boot tooling as well. https://github.com/Foxboron/sbctl

Enabling secure boot for your Arch installation is very easy now with the "sbctl" tool
No problem! The sbctl package ships with a pretty extensive hook out of the box (https://github.com/Foxboron/sbctl/blob/master/contrib/pacman/ZZ-sbctl.hook). It's been very reliable for automatically resigning .efi executables after updates for me.

sbctl fails to find EFI system partition
sbctl verify returns failed to find EFI system partition despite it definitely is there. It's the same issue as this but remounting or restarting doesn't fix it.

Setting up secure boot while dual booting Windows 11 and Arch Linux
By far the easiest is to use sbctl to generate, install and use keys to sign your efi images. You can use mkinitcpio to build the unified kernels automatically and a pacman trigger to rerun the sbctl signing when the kernel is updated. Pretty straightforward (once you've done it once).

Intel OEM Private Key Leak: A Blow to UEFI Secure Boot Security
The question is whether you have any UEFI drivers or not. If they're in the ESP you can just look there to check, but UEFI drivers can also be loaded from PCI cards or baked in the firmware itself.
If you're using a TPM for Secure Boot, you can use the command in https://github.com/Foxboron/sbctl/wiki/FAQ#option-rom to know for sure.
