I've bought a new keyboard off ebay and they've sent me an american one.
On my laptop i changed the keyboard to english (US) and all the keys were mapped as printed.
When i try to change my keboard country on my Raspberry pi nothing happens. From the raspberry menu i click `preferences` then click `mouse and keyboard settings `. Click the `keyboard` tab. When i click the `keyboard layout` button nothing happens
Also when i change my mouse speed. Click ok, re-open `mouse and keyboard settings` .
The mouse speed is back at it's initial value.
By the way it's a raspberry pi 3b+ running rasbian.
