My first thought would be to try a different kernel.

Did this computer come with the 5.10-oem kernel? I'm wondering why you are using it instead of the 5.11 kernel which is available in Update Manager.

There is also a 5.13-oem kernel available.

This was the natural update of linuxmint

The 5.10-oem kernel is only a natural update of Linux Mint if you had the 5.6-oem kernel installed prior to the 5.10-oem kernel. Those OEM kernels are not the normal Mint kernels.

If you want to try the newer kernels to see if they help, you can install the 5.11 kernel using Update Manager.
Instructions for upgrading to the 5.11 kernel:

Open Update Manager.
Select View > Linux Kernels and click Continue.
Make sure 5.11 is selected on the left panel and then click the top-most option on the right panel. An "Install" button will appear.
Install the kernel and then reboot for it to become active.

To install the latest 5.13-oem kernel, open a terminal and type (or cut and paste) sudo apt install linux-oem-20.04c and reboot.

If they do not work, you can always get back to an older kernel by booting into grub, selecting Advanced Options, and then selecting the older kernel from the list. You would then go into Update Manager and remove the newer kernels.

This is the first time I'm hearing of this type of problem, so I do not know if the newer kernels will help.

I check the history o kernel and in some moment the kernel update
change to oem , i don't know why

I try to instal generic kernell again

Bruno

UPDATE : with generic kernel , not works rtw89 module for wifi 8852

and appears a message about a firmware problem about video acceleration

i don't know wich kernel is the best for my machine

Bruno

well , i install finally generic kernell , and compiles rtw89 ( git ) module driver for 8852 wifi

You did not get a warning message about hardware acceleration with this kernel, did you? That message means the video driver did not install. You do not want to get that message.

No , I install extra modules file , and no get this message

While typing, is a thumb accidentally touching the Touchpad? My suggestion is go to settings and switch off the Touchpad if a mouse inserted or switch it off while typing. You have the two options. If no mouse, try the second option.

All I can suggest is the next time that happens, run the following in a terminal:
dmesg -T | tail -n 100
Maybe there will be an error message we can investigate.

I do not see anything in the output that gives me ideas of what might be happening.

Since you originally posted, a newer 5.14-oem kernel became available. Maybe switching to it will help because your computer is very new.

Install the latest 5.14-oem kernel with sudo apt install linux-oem-20.04d and reboot.

Okay. I just wanted to let you know than in the time that has passed since you started this topic more new kernels became available. It is possible a newer kernel might help with the keyboard issue.

Did you upgrade to the newer kernel with the terminal command I gave you or did you just update the kernel using Update Manager?

What is the output of

Code: Select all

uname -r

If it does not have 5.14-oem in the name, then please run the following command in a terminal and then reboot the computer.

Code: Select all

sudo apt install linux-oem-20.04d
