update-grub doesn't exist on TPM FDE installs, changing /etc/default/grub doesn't have any effect
If I escape to the grub menu early on I only have a single "run" option and when I hit c to edit it I have no kernel options to modify. It just specifies the rootfs. Looking at https://ubuntu.com/core/docs/full-disk-encryption: "TPM-based FDE seals the FDE secret key to the full EFI state, including the kernel command line, which is subsequently unsealed by the initrd code in the secure-boot protected kernel.efi at boot time." Which explains why my system fails to boot when I modify it. Not sure how to debug this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2084107 Title: Splash does not show up on Ubuntu 24.10 with TPM FDE To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/2084107/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
