Lock screen - keyboard layout change

Asked by rafting300

I couldn't log in into my account until I figured that Y and Z keys changed places. This could be if the keyboard layout changed somehow in the background. I have two layouts defined in the Settings-> region&language->input sources, English(US) and Serbian(Latin).
This happens randomly as far as I can tell, after a system standby or fresh boot.
This keyboard layout change should not take place, also I guess it could be helpful to have keyboard layout UI on the lock screen somewhere.

"gnome-control-center navigate to Region & Language -> Input Sources. In the header bar, hit the Login Screen toggle button and then choose a keyboard layout from the list"
I don't have a Login Screen toggle button since I have only one system user
but
in terminal localectl command printed this:
System Locale: LANG=en_US.UTF-8
       VC Keymap: us
      X11 Layout: rs
       X11 Model: pc105
     X11 Variant: latin

After applying:
localectl --no-convert set-x11-keymap us pc105

output changed to:
System Locale: LANG=en_US.UTF-8
       VC Keymap: us
      X11 Layout: us
       X11 Model: pc105

After an initial test(restarting and logging out and in a couple of times) it works as expected. I will confirm the problem solved after i give it some time Ideally after system update since the problem first manifested after a system update.
