USB keyboard not working on Ubuntu server 1.0.6

VIM3

I installed Ubuntu server focal on EMMC (VIM3_Ubuntu-server-focal_Linux-4.9_arm64_EMMC_V1.0.6-210520) and there are two problems:

  1. USB keyboard not working
  2. Strange logo transformation (see video: https://youtube.com/shorts/EWxexiDK4xg?feature=share)
  3. It’s okay?
root@Khadas:~# systemctl status plymouth-start.service

How I should fix this?
Thanks!

P.S. And yet: how I can on/off display?
I’m beginner in these theme, please sorry if some questions may seem stupid)

How about other USB devices?

What’s the output of lsusb ? And please provide the kernel log.

Yes, it’s OK. There are 3 logos will display during the bootup.

  • Uboot logo (Khadas Logo)
  • Kernel logo (6 small Khadas Logos)
  • Ubuntu logo (Khadas Logo & animation)

If you don’t want them, you can follow the doc to disable it.
