Dual monitor setup with Wayland not working

[Simon Colston <simon@xxxxxxxxxxx>]

Hi,

I am using Fedora Workstation 36 and have 2 monitors connected via HDMI to graphics on the motherboard (Intel) and a 
nvidia graphics card.

Everything works fine when I log in using Xorg.

However, if I log in using Wayland, the monitor connected to the motherboard stays blank.  The monitor is detected in 
Settings and appears to be 'working' i.e. if I move a window to the blank monitor I can click on it and it works as 
expected, it's just that nothing is displayed on that monitor.

Do you have any suggestions as to how I could make this setup work with Wayland?

Below is come information which I thought may be helpful.
