[XPS 15 Early 2017 9560 kabylake] Making Nvidia Drivers + (CUDA 8 / CUDA 9 / CUDA 9.1) + Bumblebee work together on linux ( Ubuntu / KDE Neon / Linux Mint / debian )

XPS-15 9560 Getting Nvidia To Work on KDE Neon

# Instructions for 4.14 and cuda 9.1
# If upgrading from 4.13 and cuda 9.0
$ sudo apt-get purge --auto-remove libcud*
$ sudo apt-get purge --auto-remove cuda*
$ sudo apt-get purge --auto-remove nvidia*
# also remove the container directory direcotory at /usr/local/cuda-9.0/

# Important libs required with 4.14.x with Cuda 9.X
$ sudo apt install libelf1 libelf-dev

# Install Intel Graphics Patch Firmwares (This should reboot your system):
bash -c "$(curl -fsSL http://bit.ly/IGFWL-install)"

# Update to 4.14 kernel. nvidia-384 compiles fine with this.

sudo dpkg -i *.deb

# Add Nvidia repository
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update

# Install via ubuntu drivers
sudo ubuntu-drivers autoinstall

# <optional for ML Folks> Install CUDA 8 (if you're interested in using gpu for ML) ~> requires nvidia stable drivers
# This acts as repo so install it somewhere safe and do not delete
# cuda is now available with membership only, download from https://developer.nvidia.com/cuda-release-candidate-download
sudo dpkg -i cuda-repo-ubuntu1604-9-0-local-rc_9.0.103-1_amd64.deb
sudo apt-key add /var/cuda-repo-<version>/7fa2af80.pub
sudo apt-get update
sudo apt-get install cuda
# Update Path to have /usr/local/cuda/bin incase using dotfiles.

# <optional for ML Folks> Install CuDNN for running things like tensorflow
# Download cudnn7 for cuda9 from nvidia https://developer.nvidia.com/cudnn
sudo dpkg -i libcudnn7_7.0.2.43-1+cuda9.0_amd64.deb

# Testing cuda.
$ sudo prime-select intel
$ nvidia-smi
# This should give an error, no drivers found
# Try this
$ sudo prime-select nvidia
# displays CUDA info.

# At this point the nvidia drivers work well enough. Search for "nvidia x server settings"
# in your applications menu and you can switch between intel and nvidia PRIME profiles.
# But the nvidia card is still ON (bbswitch will report it off, but the battery consumption is (20 +- 5) Watts

# You can leave it here if you're not worried about battery but if you are then continue with this.
# Install powertop
sudo apt install powertop

# TLP interferes with bluetooth, better not install it, or remove it completely.
sudo apt remove --purge tlp

# Run powertop:
sudo powertop
# You should see battery discharge around 20w +/- 5W, this eats up my battery 4 times faster.

# Add command line params:
sudo nano /etc/default/grub
# Make the following look like this, do not ask why.
GRUB_CMDLINE_LINUX_DEFAULT='pcie_port_pm=off acpi_backlight=none acpi_osi=Linux acpi_osi=! acpi_osi="Windows 2009"'
sudo update-grub2

# Install bumblebee - now this is the danger zone, this software has not been updated in a while and I am not sure when will this available.
# Avoid updating your system if you're fine with this.
sudo add-apt-repository ppa:bumblebee/testing
sudo apt update
sudo apt install bumblebee bumblebee-nvidia

# at the time of writing this, the latest is nvidia-381 but cuda 8 requires the stable, which is nvidia-375
# add them to bumblebee config file.
sudo nano /etc/bumblebee/bumblebee.conf

# Change 'Driver=' to 'Driver=nvidia'
# Change all occurences of 'nvidia-current' to 'nvidia-xxx'
# Change KernelDriver=nvidia-384

# save and run
sudo service bumblebeed restart
# this should give you daemon already running
sudo bumblebeed 

# Since the driver load will now be handled by bumblebee, we need to stop the OS from loading it.
sudo nano /etc/modprobe.d/bumblebee.conf

# Make the following section look like this (the drm line will be added):
#387
blacklist nvidia-387
blacklist nvidia-387-drm
blacklist nvidia-387-updates
blacklist nvidia-experimental-387

# once that is done, you'll need bbswitch dkms module
sudo apt-get install bbswitch-dkms

# Load this with the kernel.
sudo nano /etc/modules-load.d/modules.conf
# add following
i915
bbswitch

# now make sure nvidia-settings has nvidia prime profile selected.

# So what actually happened:
# The control for switching between graphics has been moved from nvidia's driver to bumblebee. This helps
# maximize battery life because now you can selectively switch between which graphics card to use. In case
# you want to provide access to nvidia gpu for the current application run it using optirun.
# e.g. if you want to run steam with nvidia gpu, run something like: $ optirun steam
# or if you're using gpu to run ml tasks, just run them with optirun and they would work just fine.

# Additional
# TLP is known to interfere with bumblebee, make it avoid using this https://wiki.archlinux.org/index.php/Talk:Bumblebee#Bumblebee_and_TLP_interferening
# Run powertop to see if battery consumption is in check: 10w +/- 5W

# Testing bumblebee
cat /proc/acpi/bbswitch       # Ouput:0000:01:00.0 OFF
optirun glxgears -info        # Runs the Gears demo
optirun nvidia-smi            # Should give an error
sudo prime-select nvidia      # Should select nvidia hardware for cuda
optirun nvidia-smi            # Outputs:

cat /proc/acpi/bbswitch       # Still Outputs:0000:01:00.0 OFF which means, we're using nvida hardware only when we run applications using optirun

# Getting mouse freezes, random misses?
dmesg -w | grep psmouse  #check if your trackpad is out of sync frequently

# Add this boot flag:
"psmouse.resetafter=0"

# The system loads a blank screen with just a cursor on reboot?
# I found that selecting nvidia and restarting the system would need nvidia to run again,
# but unfortunately we disable nvidia on startup. A simple fix could be adding an alias in your ~/.(bash|zsh)rc
# I always restart my system from the terminal so this makes sure I move back to intel always before restart.
alias reboot="sudo prime-select intel; sudo reboot now"
alias shutdown="sudo prime-select intel; sudo shutdown -h now"
