Lock screen sometimes locks keyboard

Support
1

When i let computer go into lock screen and then i have to enter the password sometimes the keyboard is locked and the only way is through the virtual keyboard.
Is it why there’s a virtual keyboard available? Is it supposed that happens?

2

no - that should not happen. Which system, which desktop enviroment? Is it a build in keyboard or USB? (or even PS/2 still)?
