# Check the defaut run level
systemctl get-default
#Check the graphical.target status
systemctl status graphical.target

systemctl set-default graphical.target
#start and enable the graphical.target
systemctl start graphical.target
systemctl enable graphical.target
#Now lets check the status again
systemctl status graphical.target
systemctl get-default
