Keyboard stops working after upgrade to 21.04

[zeezam]

Hello,

Installed Ubuntu on my Pi 4 Model B via Raspberry Pi Imager.

Everything works fine until I upgrade to 21.04, then keyboard stops working after I sign in.
Mousepad still works. I'm using a Logitech K400 keyboard with bluetooth usb adapter.

Tried sudo apt-get install xserver-xorg-input-all but same problem remains. Also tried removing first with --purge.
If I reinstall Ubuntu - everything works fine until upgrade.

Anyone who ran into this kind of problem and was able to solve it?

Maybe running an old version Ubuntu is the solution but then the graphic driver causing wrong resolution.

Cheers.

Are you on Wayland? Try to log into the xorg session (choose this from the login screen) and see if it makes a difference.

Did it do a kernel update?

uname -a

Can you still see it in the USB dev's

lsusb
lsusb -t

If you interupt the Grub Menu, select other, and use an earlier kernel does it work?
On other, what Graphics Server are you using? Xorg or Wayland?

It works with xorg session
It's now default. I can just use Ubuntu xorg session instead of Ubuntu?

Thank you!

I havn't tested this yet. Seems to work now with xorg so I maybe not need to do this.
There is no grub on raspberry pi. It doesn't boot that way.
See my answer above for Xorg/Wayland.
Thanks.
