Yes, I know that I just type 'startx' to enter graphical mode, but in my case there is no 'startx' command. Installing Openbox didn't trigger X11 but Wayland. And that's why I posted this issue here.

Huh. I hadn't noticed this. I mean, I know Wayland is installed, but running Openbox with lightdm, my X session starts just fine.
What packages did you install before attempting to start your session?
BTW, startx starts X.
