I'm confused because everything I read about Nvidia and Wayland says that a Nvidia proprietary graphics driver is needed to run Wayland with an Nvidia graphics card.
I did try to run Wayland and I was using an Nvidia proprietary graphics driver and I was unable to enable Wayland as the settings gear on my log in screen wasn't available.
Today I decided to reinstall Ubuntu 20.04.2 on the same computer only this time I didn't use the Nvidia proprietary graphics driver and to my surprise I now have the option to use Wayland I am using Wayland and so far it appears to be working well.
Why does the Nouveau open source driver work and since it does work why does anyone need the Nvidia proprietary graphics driver if the Nouveau open source graphics driver works.
Thanks.
