How do I change the default runlevel?

systemd uses symlinks to point to the default runlevel. You have to delete the existing symlink first before creating a new one rm /etc/systemd/system/default.target



Switch to runlevel 3 by default ln -sf /lib/systemd/system/multi-user.target /etc/systemd/system/default.target



Switch to runlevel 5 by default ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target
