Fresh install 24.04 and no brightness controls with AMD CPU GPU

Evening all,

So I have just installed a fresh copy of 24.04 and I now have no brightness controls, using the keyboard shortcuts, brightness slider in the battery system tray or using the cli via brightnessctl app.

I have disabled the discrete 3060 and will leave that disabled so need brightness controls via the integrated AMD GPU.

Is anyone able to tell me what I need to do to get back brightness controls please?
