Was it a version upgrade (from 17.04 to 17.10) or a fresh install?
In any case, and if I understand it correctly, the GDM greeter, which is the default greeter in Ubuntu 17.10, allows you to use the keyboard layout(s) stated in the /etc/default/keyboard file. That file probably includes this line:
XKBLAYOUT="az"
while you would like that line to read:
XKBLAYOUT="us"
or maybe
XKBLAYOUT="az,us"
If you - as in the latter case - state more than one layout, the GDM greeter will provide a keyboard layout switcher.
So I guess you need to fix this somehow, maybe by starting your computer with a bootable USB stick.
