I have FI - Finnish and FI - Finnish (Windows) keyboard layouts enabled in Kde (no US layout at all), but every time I reboot and login the layout is US until I manually change it. How do I get rid of US layout permanently?
One possibility is a wrong setting in YaST. The YaST setting should be the same as the physical keyboard. Then KDE can make the conversions from the hardware layout to the software layout.
I finally figured it out, I had installed Zoom which in turn installed IBUS which seems to cause this issue.
…Goodbye IBUS and Zoom.
