If I log in choosing 'Gnome-xorg' and check I get the SAME:
loginctl show-session 2 -p Type
Type=wayland
echo $WAYLAND_DISPLAY
wayland-0
I can't reproduce that in a VM. Please file a bug and send a link.
I see this on a Lenovo T550 with only Intel integrated graphics
and on a Dell Inspiron with hybrid graphics, optimus, nvidea+intel.
It would be great if you could participate in tomorrow's test day [1], you can then
debug the issues with dual graphics plumbing developer (Hans de Goede) directly.
Thanks a lot.
