I have simulation that requires 30 out of my 32 GB of RAM. Unfortunately, Pop!_OS and its Desktop Environment take a little bit more than 2 GB. This means I cannot run my simulation. I tried installing other desktop environments but they still consume > 1 GB. This is why I want to boot without the graphical interface

I have extensively googled how to achieve this but I only find answers for Ubuntu. People talk about GRUB options but I'm using an Oryx Pro (so it's also System76 hardware) and I am using its default bootloader, not GRUB.

  • Before GUI starts, can you start in Terminal using Ctrl Alt F1 or F2? That allows me to boot into Kali terminal only.

  • @John, all that does is switch the display. It does nothing to the running processes. The gui still runs, albeit, with only the gui login screen.

You want systemctl set-default multi-user.target which will mean no gui will start on boot.

To disable the gui when already running, systemctl isolate multi-user.target

systemd run levels will give you a bit more info.
