Keyboard issue after suspend

[entrey]

Hi!

I have switched from Win10 some about a month ago and using Linux Mint 20.1 since.

Earlier, as a Win user, i used to turn my PC into Suspend Mode from time to time, but it appeared that I'm encounter some strange issue if trying to do so inside Mint.
So the problem is that after wakinging my PC out of suspend mode the keyboard stop responding. For example i can see the green light above NumLock button, but i cannot turn it off. Therefore there is no way to type my password on a Welcome Sreen.
What i can do is activate screen keyboard with my mouse (which is working normally) and type password with the help of it. But even after I get inside desktop interface the keyboard will not respond to any keystrokes, so the only option i found is climb under the table, find the keyboard connection cable, unplug it and plug back in. After such manipulation everything start to works normally.

The keyboard works fine in all use cases except the abovementioned when I try to turn on the PC after being suspended.

Thanks for any advice.

Did some additional research and this time found a couple of old posts pointing to the same problem.

For example this one.

I also have tried this solution but unfortunately it doesn't help in my particular case.

Still researching...

Are we talking about a wired or wireless keyboard?
