Change Wayland to Xorg in Ubuntu 17.10

These days I was testing Ubuntu 17.10. I like it, but when I turn on my PC (with Ubuntu 17.10), in the ‘‘login screen’’ works Wayland, and my GPU doesn’t support it. After login, it automatly change to Xorg and it works normally.

How can I change Wayland to Xorg in the ‘‘login screen’’?

I’ve moved this to the category because this site isn’t designed to take tech support questions. Sorry. I’d recommend using one of the official support channels listed on the Finding Help page.

Hint: Look for the gear icon on the login page.
