Bug Description
Impact
------
If you use virt-manager or gnome-boxes from a 22.04 host to install a 22.04 VM, the VM tries to use Wayland by default and only shows a black screen (caused by bug #1971195).
Test Case
---------
1. Install the osinfo-db update and gnome-boxes
2. Close GNOME Boxes if it's running. Open GNOME Boxes.
3. Click the + icon, then Create virtual machine from file. Select your Ubuntu 22.04 desktop ISO.
4. Follow the prompts to create your box.
5. After it finishes installing, click the box. Log in. The screen should show like normal.
What Could Go Wrong
-------------------
This disables the 3D Acceleration (virgl) feature. The 3D Acceleration feature is disabled by default (you have to manually enable it even after installing a distro where it is offered).
And you have to toggle the switch to keep it working:

It's not clear why this black screen bug occurs, but there is an easy fix to revert a not very useful feature that only landed in 22.04 about a week ago.

The suggestion worked. With this diff:

I could login on the jammy vm without having to switch to Xorg.
This is not a review: I don't know what other impact the suggested change has.
