I am fairly new to the world of Linux. This morning I installed Ubuntu 21.10 on my Fujitsu Lifebook U749. It's working good but I have the problem that the laptop keyboard stops working after running sudo apt update followed by a reboot. A USB keyboard I attached works. I get the laptop keyboard working again by running sudo apt remove xserver-xorg-input-all followed by sudo apt-get install xserver-xorg-input-all in the terminal. The keyboard will then work again after a reboot. If I then run a sudo apt update again, and reboot the system, the keyboard is 'broken' again.
How can I resolve this issue so doing sudo apt update doesn't break my keyboard?
sudo apt updateby itself does absolutely nothing, as in no change whatsoever. As such it CANNOT be the cause. – ChanganAuto Jan 28 '22 at 14:06
