Sometimes I would like to boot my laptop running Debian with GNOME 3 normally, however sometimes I would like to boot into text mode without having to manually stop the gdm3 service. Currently, I have to either manually stop gdm3 when the computer is booted or I have to boot into text mode and manually start the service.
How can I add an option (perhaps in the GRUB menu?) that will allow me to boot into a different mode if I choose?
