When I login on a Fedora 31 workstation and run the ps command, I see the below output;
for an X session:
for a Wayland session:
As I understand, graphical logins via a display manager like gdm executes an X/Wayland session directly after authenticating a user, instead of executing a login shell. I see that both X and Wayland sessions are started on a virtual terminal (tty2), and what the Xorg(1) says about the vt option is: 'This option applies only to platforms that have virtual terminal support, such as Linux, BSD, OpenSolaris, SVR3, and SVR4.' Is starting X/Wayland sessions with a controlling tty done merely to provide the ability to switch to other virtual terminals while running a graphical shell in one, or is it a constraint of X/Wayland? Is it possible to start an X/Wayland session without a controlling tty on Linux, and is this up to gdm, X/Wayland, or systemd? And what would be an example of a system that runs Xorg and doesn't have virtual terminals at all unlike the systems listed in Xorg(1)?
