Wrong keyboard layout at login screen
Hi, I have a really bizarre problem.
The layout of the Swiss-German keyboard is different from the US layout, e.g. "z" and "y" are reversed. My user password contains a "z", let's assume it's "Gazebo.1".
When I try to log in with "Gazebo.1", I get an error message. However, when I log in with "Gayebo.1", it works. Afterwards, all is in Swiss German, user interface, keyboard layout, etc. I don't even have the US keyboard layout available in the system settings.
I had the problem that the login screen was in English, e.g. I saw "Guest User" instead of the German word "Gastbenutzer". I was able to change that with the terminal command "sudo languagesetup". I guess I need to do something similar to change the startup keyboard layout.
Any hints what to do?
