Install guide for Elementary OS on Dell XPS 15 9560

Installing elementary on XPS 9560

# Install Elementary like you normally would, after install disable dGPU
# If you don't need your dGPU in Linux: https://gist.github.com/jseris/a740f6a3fb0d18064e26dc66f9be4f1d

# If you want to use your Nvidia GPU:
sudo apt install nvidia-375 nvidia-prime

##### Seems this is fixed #####
# Don't restart yet, the version of nvidia-prime that is shipping does not work
# cd /usr/bin && sudo mv prime-select prime-select.old
# sudo wget https://raw.githubusercontent.com/C11235/nvidia-prime-bugfix/master/prime-select && sudo chmod 755 prime-select

# After reboot changing the gpu in settings should work

# Just some notes
# By default Elementary doesn't let you add ppas, to fix this:
sudo apt install software-properties-common

# To install tweaking tool
sudo apt install software-properties-common &&
sudo add-apt-repository ppa:philip.scott/elementary-tweaks &&
sudo apt update &&
sudo apt install elementary-tweaks

I think it is not for installing elementary OS but a script for Initial elementary OS installation. Thank your for that because I work for a lot of automating for elementary OS initial installation here : https://github.com/LinkPhoenix/ElementaryOS_Initial_Setup
