I am running Ubuntu 16.04.6 LTS ( Mate, built with ubuntu-mate-16.04.2-desktop-armhf-raspberry-pi.img ) When I initially built this, I enabled the auto-login when going through all the initial questions. But now, after it is built and doing what I want, I wish to disable the GUI and have it boot to the CLI. I went through the usual raspi-config and changed the Boot Options + Desktop/CLI, and selected CLI. But when I boot, it does go to CLI, but networking doesn't seem to be working unless I actually log into the CLI as the user I initially created. I tried waiting several minutes, but the networking will never come up and I can not connect to the pi remotely unless I log into the CLI console first. So, the only thing I can think of is there is some setting confused due to the pi initially being setup with auto-login. So, I re-enabled the GUI login and rebooted. Upon doing so, networking works after boot as it did before. I'm now trying to see if I can disable the auto-login at the GUI. Then, I'll try to do the raspi-config again and change it to CLI login. But I can't find anywhere to disable the user from auto-login. Where is that setting? Does it exist? Or did I just stumble upon a bug?
