I've been following a youtube tutorial to install arch linux (using virtual box) and it led me to a problem that i have no clue how to solve. Whenever i try to boot Arch it gets stuck at reached target Graphical interface. There is no escape from here no matter what i do (i tried ctrl-alt-f2 but it just return in a second). The last thing i did was:   sudo systemctl enable lxdm.service (then a reboot). I don't know if that is enough info to solve my problem or not. PS: a google search shows that many people have had similar problems but all the solutions are impossible to do as i am trapped on the boot screen.
