Public bug reported:
I installed Ubuntu on a MicroSD card in a Microsoft Surface Pro in
order to arrive at a dual boot installation. I followed these great
instructions: https://vitobotta.com/2018/01/11/ubuntu-full-disk-
encryption-manual-partitioning-uefi/ to make sure key partitions were
full disk encrypted.
I expected to be able to enter my disk (de)encryption password at boot
in order to continue booting into Ubuntu and Gnome.
Unfortunately, I could not type from the Surface Pro typecover to enter
the disk decryption password.
As a workaround, I plug in a USB keyboard - which allows me to enter the
password and boot normally into Ubuntu. After entering the password, I
can remove the USB keyboard and load the OS where typing from the
Surface Pro typecover works fine (on it now).
If I enter Grub menu/prompt before this decryption prompt, the typecover
works fine...but seems to stop working after the Grub menu.
