Keyboard stops working whenever powered off

Question

I recently installed Ubuntu (20.04 LTS) on my laptop (Asus ZenBook 13 OLED UX325). It works for the most part but I realized that whenever I use the power off option, the keyboard will not work upon restart. Basically, I need to (from another question)

sudo apt-get install xserver-xorg-input-all

or

sudo apt-get --purge autoremove xserver-xorg-input-all
sudo apt-get install xserver-xorg-input-all

after using the Screen Keyboard to log in. I also have to be careful to push Restart instead of Power Off after written the commands in the terminal.

Needless to say, I wish to not have to do this tedious (and temporary) routine every time I Power Off my computer. Surely there must be a permanent solution?

Edit 1: It also appears to work if I log in using the Screen Keyboard after Power Off and then just Restart again. No real need for the commands above. Power Off is the prime suspect.

Edit 2: I do not really have to log in. After Power Off, I can just Restart before logging in, and then the keyboard works afterward. Power Off must be the perpetrator, no?

Thank you, @nobody. I wrote what you said but there was no output in the terminal. Any ideas? — naughty_waves, Aug 17 '21 at 17:45
Sorry no. I thought it has to do with this. https://askubuntu.com/questions/1280217/why-is-my-laptops-keyboard-screwed-up-since-kernel-5-4-0-47-till-5-8-0-20 — nobody, Aug 17 '21 at 17:49

1st > Update UEFI 2nd> Fully update the OS. Does the symptom persists? — ChanganAuto, Aug 17 '21 at 18:20
Thank you, @ChanganAuto. The newest BIOS version is already installed (Version: 301). By fully update the OS, do you mean sudo apt-get update or something more elaborate? — naughty_waves, Aug 18 '21 at 07:29

I had the same issue with my ASUS Zenbook 13 UM325S. (Kubuntu 20.04.3) I tried to follow the same steps as you but had no success.

I found that there is some issue with the latest kernel version. I just reinstall Kubuntu 18.04.5 and the issue is solve.

It's not a 100% solution but I do not want to restart every time.

I hope this will help you also.

Thanks

The question is about 20.04 and your answer addresses 18.04. Not sure this makes any sense. – Artur Meinild Aug 31 '21 at 20:49
Thank you, @Nirav. It could perhaps be solved (as you state) by downgrading to Ubuntu 18.04.5 but I still feel like this is something that should be fixed for future versions. I will have to live with having to restart an extra time for the time being. – naughty_waves Sep 02 '21 at 12:11
