Use case:
1. install gnome-session or gnome-classic or unity, you will end up with additional xorg session.
2. Log in on a system you don't have wayland capability
-> you will be fallback to a random xorg session, being vanilla gnome, or ubuntu-xorg, or gnome-classic or even unity.
-> we should insert "-xorg" flavor for current session on fallback to get that one on the stack and ensuring we possibly fallback to a compatible session.
