Collection of scripts and tweaks to make Ubuntu 18.04/20.04 run smooth on Dell XPS 15 9570. I suggest everyone to use the post install method, the respun ISO is no longer supported nor neeeded for booting Ubuntu on 9570 as the stock one contains the needed fixes.

All informations, tips and tricks was gathered from:

• tomwwright gist for DELL XPS 15 9560
• Atheros wifi card fix
• Respin script and info
• Myself xD

Kudos and all the credits for things not related to my work go to developers and users on those pages!

What works out-of-the-box

• ✅ Atheros Wifi
• ✅ Audio
• ✅ Audio on HDMI
• ✅ HDMI ( even on lid closed )
• ✅ Nvidia/Intel graphic cards switch
• ✅ Keyboard backlight
• ✅ Display brightness
• ✅ Sleep/wake on Intel
• ✅ Sleep/wake on nVidia

What doesn't work

• ❌ Goodix Fingerprint sensor

Post-install script

If you already have a standard Ubuntu install, you can try applying basic tweaks with the xps-tweaks.sh script. You can run it directly without cloning the repository with the following command (requires curl):

bash -c "$(curl -fsSL https://raw.githubusercontent.com/JackHack96/dell-xps-9570-ubuntu-respin/master/xps-tweaks.sh)"

If you want touchpad gestures using X11, check https://github.com/bulletmark/libinput-gestures or better https://github.com/iberianpig/fusuma.

How to switch from one graphic card to the other

Starting from nVidia 435 drivers, we can finally offload apps like on Windows without having to use very complicated setups with Bumblebee. If during the script you chose to not enabling offloading, you can use the classic prime-select command:

Intel:

sudo prime-select intel

Nvidia:

sudo prime-select nvidia

Note: A full reboot could be required when switching graphic cards.
