I'm trying to install Linux mint on my new ax16 pro laptop but keyboard doesn't work as expected. For every key pressed the character will be printed 8/9 times
I've tried to set rate and delay using Linux utils but this doesn't solve the problem!
To complete distro install I must use external keyboard and then the problem is still present.
This will happened with many Linux distro at their latest version. I've tried Linux mint, Manjaro e elementary os : those distro have keyboard multiptress problem.
Older version (Linux mint 20.3) doesn't have this problem neither windows.
Anyone faced this problem?

I haven't seen this before, but other Mint users have experienced it on different systems. I would check on the settings in Mint, like mentioned here: https://forums.linuxmint.com/viewtopic.php?t=172398

Thanks for your reply, unfortunately it doesn't work
changing rate and delay was my first attempt

It may be a difference in the drivers between your older Linux distro and your newer one. Can you check what version they're on?

I would do it willingly but this is not simple task : how can I do that?
You mean lsusb command?

A google search tells me lsmod should help. Sadly, I'm not as familiar troubleshooting Linux issues as I am with Windows, so I'm just using similar troubleshooting methods.

Solution found!
To make the keyboard works with any linux distro extra kernet param must be added at boot!

So, you must edit grub settings: and change line in
then update grub and reboot
It works like a charm!
