I've set up Ubuntu 16.04.3 LTS to boot in CLI mode, and to start a GUI I run sudo lightdm start in tty1.
My question is, Is there any way to quit GUI completely and get back to CLI in GUI?
I can quit GUI by sudo lightdm stop in tty2 (since tty1 is running lightdm and I can't insert any command) or simply by CTRL + C. But it feels like an unusual way to me. And am I doing right to quit GUI?
