i had long search to complete my ubuntu 20.04 installation on the new dell XPS 13 . here is the steps to have all the things gathered together
- install base image ubuntu 20.04 with a usb stick
- on the first boot you will have no drivers installed , what you need to do is to connect your PC with an RJ45 (with a usb C to RJ45 adapter) 2.1 launch sudo apt update 2.2 sudo apt upgade
- next you will need to install additional drivers so that your system will be Ubuntu Certified :https://certification.ubuntu.com/hardware/202007-28046 3.1 run : apt install linux-oem-20.04
- to activate finger print and face recognition : 4.1
