Not sure if it is the same issue, but sounds very similar. Situation: GRUB freezes on my laptop at countdown 10 with not ability to move anything. Currently, this happens everytime my external keyboard is attached.
Equipment: HP X360 i7 configured dual boot. USB 3.1 (USB-A), USB 3.1 (USB-C) and Thunderbolt (USB-C). UEFI Boot. This is an issue because I want to leave my computer docked and survive a reboot without having to unplug the keyboard all the time. I've googled solutions and "legacy boot" would disable my installed OSs. There is not bios option for "legacy USB" support and none of the GRUB-2 configurations to enable USB, usb-keyboard, etc... have worked. MY KEYBOARD works before and after grub.... meaning, that at power-on, I can press F10 on usb-keyboard and get to BIOS. Plugging in the keyboard after GRUB boot, keyboard works. I have tried three separate keyboard... all of which I know are working. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1448668 Title: Grub menu hangs on down arrow press with USB keyboard on cold boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1448668/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
