Public bug reported: 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. ** Affects: grub2 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1897462 Title: GRUB2 freezes after removing at_keyboard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1897462/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
