Public bug reported:
Steps to reproduce:
1. On a jammy host, create a jammy guest:
$ qemu-img create -f qcow2 vm.qcow2 50G
$ qemu-system-x86_64 -accel kvm -cpu host -smp cpus=4 -m 3072 -device
virtio-vga -display gtk,grab-on-hover=on -hda vm.qcow2 -cdrom [jammy ISO]
2. Install Ubuntu in that VM (minimal install), no problems are expected
yet.
3. After the installation is concluded and the VM reboots, try to login
using the Wayland session (it should be the default, no need to select
anything). It will fail and bring you back to the login screen
(apparently due to a gnome-shell crash; I don't think the details are
relevant to the problem here).
What is expected: that both the Wayland and X11 sessions work out-of-
the-box.
Workaround: remove gnome-remote-desktop, and the Wayland session will
work just fine in the conditions described above. This is why I'm
reporting this issue in gnome-remote-desktop instead of Wayland or
gnome-shell or qemu. I might be wrong though...
Extra information:
1. gnome-shell starts as expected if the X11 session is selected instead.
2. Alternatively, using the OpenGL enabled virtio-vga driver also makes it work
in both the X11 and Wayland sessions:
$ qemu-system-x86_64 -accel kvm -cpu host -smp cpus=4 -m 3072 -device
virtio-vga-gl -display gtk,gl=on,grab-on-hover=on -hda vm.qcow2
