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 update` by itself does absolutely nothing, as in no change whatsoever. As such it CANNOT be the cause. – ChanganAuto Jan 28 '22 at 14:06
  • Maybe one of the solutions on [here](https://askubuntu.com/questions/1269284/keyboard-not-working-after-update-18-04-20-04?rq=1) can help. – random person Jan 28 '22 at 14:17
  • @ChanganAuto Precies! Ik vond het apart dat het toetsenbord werkte maar nadat ik Brave installeerde via de terminal, een reboot deed het opnieuw stuk was. – ThyArtIsMurder91 Jan 28 '22 at 14:31
  • @randomperson Thanks, will check that! – ThyArtIsMurder91 Jan 28 '22 at 14:32

    The problem seems to happen randomly I've noticed. Sometimes it works after a reboot, sometimes it doesn't... – ThyArtIsMurder91 Jan 28 '22 at 18:56
  • I'm having a similar problem since today, on ubuntu 18. For me, closing the lid of the laptop and opening it again (then I have to login again) does the trick. Just logging out without closing the lid does not seem to help though. – lucidbrot Apr 03 '22 at 14:16
  • At the moment it seems like [this answer](https://askubuntu.com/a/1340274/606260) fixed it for me – lucidbrot Apr 03 '22 at 15:26
