[Bug 1897462] Re: GRUB2 freezes after loading at_keyboard

[Julian Andres Klode]

Low priority because

- this module is not built-in, and hence cannot be used on secure boot systems, so it's only usable on legacy and custom systems in the first place
- it is an usual end user configuration, given that there is not even a configuration option for it
- it's not necessary for booting the system, unless you have /boot inside LUKS and layout differences matter for the password, but that's again an unusual system configuration
- there is an easy workaround of just typing with ANSI layout in mind

Title:
  GRUB2 freezes after loading at_keyboard

Status in grub2 package in Ubuntu:
  Triaged

Bug description:
  Try these commands on GRUB command line:

  insmod at_keyboard
  terminal_input at_keyboard console
  terminal_input console

  Now GRUB doesn't accept any keypress.

  Or chainload to another GRUB with at_keyboard active on
  terminal_input. New GRUB cannot controlled by keyboard, but starts
  default menuentry after timeout.

  Module at_keyboard is important for localisation, e.g. using a german
  keyboard layout.
