keyboard not working at grub menu

keyboard not working at the grub menu, hence the ability to multiboot is lost at system start

keyboard works in bios, kwin, terminal and gui

has anyone else noticed this?

the other os’s can be pre-selected via yast

Kernel: 4.18.11-1.g4a5c1c1-default x86_64 bits: 64
Desktop: KDE Plasma 5.13.5
Distro: openSUSE Tumbleweed 20180928

the same occurs with Kernel 4.18.5-1.4 and Kernel 4.18.9-1.3

As far as I know, grub is just using the BIOS/Firmware to access the keyboard.

Is this at all similar to Bug 1101747 ?

no, Bugzilla – Bug 1101747 talks about grub-efi, and no cursor after entering the edit mode

this PC is not EUFI

the keyboard has no effect at the grub menu

any key press is ignored

Have you checked your BIOS setup? Assuming USB, perhaps Legacy USB support needs to be enabled?

Is this something that only began on updating to 20180928?

changing “Legacy USB Support” in the BIOS

from BIOS only
to Enabled

corrected the issue

thank you and to all who contributed

Glad to have been of assistance.
