## Installation

Before installing it is necessary to modify some UEFI Settings. They can be accessed by pressing `F2` repeatedly when booting.

- Change the SATA Mode from the default "RAID" to "AHCI". This will allow Linux to detect the NVMe SSD. If dual booting with an existing Windows installation, Windows will not boot after the change but this can be fixed without a re-installation.
- Change Fastboot to "Thorough" in "POST Behaviour". This prevents intermittent boot failures.
- Disable secure boot to allow Linux to boot. Alternatively, you can choose to set up Secure Boot so that it works with Linux and you can take advantage of its potential security benefits.

Installation of Arch Linux can proceed normally. Refer to the Installation guide for more information.

Note Many Dell XPS UEFI do not support passing kernel line options directly to the kernel and will result in a frozen boot. Use a boot loader or Arch-EFIBoot[1] instead.

## Firmware

They are 2 main ways to update the UEFI firmware:

- through the running Linux session with fwupd,
- through UEFI: firmware images can be found at Dell support page as `XPS_15_9570_X.Y.Z.exe` files:
  - Download the desired firmware from section "Dell XPS 15 9570 System BIOS"
  - Save it in `/boot/EFI/Dell/Bios/` (this path may vary, depending on your installation)
  - Reboot the system, and enter the boot menu by pressing repeatedly `F12` on Dell logo
  - Choose "Bios Flash Update"
  - Select the file previously saved, and start the process

  The process will take about five minutes, during which the system will have some reboots and push fans at maximum speed. Finally the system will reboot normally.

## Power Management

### Suspend

See Power management/Suspend and hibernate#Changing suspend method.

### Hibernate

Works out of the Box see Power management/Suspend and hibernate

### Powertop

`powertop` is very efficient to manage power consumption. Run `powertop --auto-tune` and compare the Watt consumption variation (laptop must be unplugged and running on battery). `powertop --auto-tune` can be run at every boot.

See Powertop#Apply settings.

## Graphics

The integrated Intel card works out of the box.

### Various options for the integrated Intel-card

TLP is recommended to save some power. However several more options can be activated for the Intel card in order to save power or prevent screen flickering.

Add the following line to:

    /etc/modprobe.d/i915.conf

    options i915 enable_fbc=1 disable_power_well=0 fastboot=1 enable_psr=0

Some guides suggest the option `enable_guc=3`, however some problem were evidenced with that option. Before you add it to `/etc/modprobe.d/i915.conf`, try it first as a command-line option before you boot.

### kernel modules

The nouveau module is known to cause kernel panics and freezes.

One way to mitigate this would be by adding `nomodeset` to the kernel options. However it is better to completely disable it with the blacklist method (recommended):

    /etc/modprobe.d/blacklist.conf

    blacklist nouveau
    blacklist rivafb
    blacklist nvidiafb
    blacklist rivatv
    blacklist nv

### NVIDIA Optimus

See NVIDIA Optimus#Available methods.

#### Disable NVIDIA card when not in use

Another good option is to disable the default NVIDIA board and enable it only for off-loading for computation purposes using PRIME.

Note This alternative drastically lowers the laptop's power consumption from around 13W to 6/7W.

It is possible to make it work with the proprietary NVIDIA driver, and there are probably several ways to make it work. See [2].

- Install nvidia-580xx-dkmsAUR and nvidia-prime. This should pull all necessary packages.
- Create the following file and add the following to allow the GPU to power-off on boot:

    /etc/tmpfiles.d/nvidia_pm.conf

    w /sys/bus/pci/devices/0000:01:00.0/power/control - - - - auto

- Several modules need to be blacklisted in order to prevent them from being loaded on boot. Add the following to

    /etc/modprobe.d/blacklist.conf

    blacklist nouveau
    blacklist rivafb
    blacklist nvidiafb
    blacklist rivatv
    blacklist nv
    blacklist nvidia
    blacklist nvidia-drm
    blacklist nvidia-modeset
    blacklist nvidia-uvm
    blacklist ipmi_msghandler
    blacklist ipmi_devintf

- Create the following file:

    /etc/modprobe.d/disable-nvidia.conf

    install nvidia /bin/false

- If you are using TLP, you might need to blacklist the discrete NVIDIA card by adding/uncommenting the following line inside the TLP config file:

    RUNTIME_PM_DENYLIST="01:00.0"

Double-check the address with lspci.

- In order to enable and disable the video card create the following 2 scripts:

    enableGPU.sh

    #!/bin/sh
    # allow to load nvidia module
    if [ ! -f /etc/modprobe.d/disable-nvidia.conf ]; then
    	printf "File /etc/modprobe.d/disable-nvidia.conf does not exist.\n"
    	printf "Is the GPU already enabled ?\n"
    	exit 1
    fi
    printf "Allowing to load NVIDIA modules...\n"
    mv /etc/modprobe.d/disable-nvidia.conf /etc/modprobe.d/disable-nvidia.conf.disable
    printf "Changing power control...\n"
    # remove NVIDIA card (currently in power/control = auto)
    echo -n 1 > /sys/bus/pci/devices/0000\:01\:00.0/remove
    sleep 1
    # change PCIe power control
    echo -n on > /sys/bus/pci/devices/0000\:00\:01.0/power/control
    sleep 1
    # rescan for NVIDIA card (defaults to power/control = on)
    printf "Rescanning....."
    echo -n 1 > /sys/bus/pci/rescan
    if [ -x "$(command -v nvidia-smi)" ]; then
    	printf "\n"
    	nvidia-smi
    fi
    printf "\nNVIDIA CARD IS NOW ENABLED.\n"

    disableGPU.sh

    #!/bin/sh
    printf "Unloading NVIDIA modules...\n"
    modprobe -r nvidia_drm
    modprobe -r nvidia_uvm
    modprobe -r nvidia_modeset
    modprobe -r nvidia
    printf "Changing power control...\n"
    # change NVIDIA card power control
    echo -n auto > /sys/bus/pci/devices/0000\:01\:00.0/power/control
    sleep 1
    # change PCIe power control
    echo -n auto > /sys/bus/pci/devices/0000\:00\:01.0/power/control
    sleep 1
    # lock system from loading nvidia module
    if [ -f /etc/modprobe.d/disable-nvidia.conf.disable ]; then
    	mv /etc/modprobe.d/disable-nvidia.conf.disable /etc/modprobe.d/disable-nvidia.conf
    	printf "\nNVIDIA CARD IS NOW DISABLED.\n"
    else
    	printf "\nFile /etc/modprobe.d/disable-nvidia.conf.disable does not exist.\n"
    	printf "Is the GPU already disabled ?\n"
    fi

- If the video card is not disabled on shutdown, then the modules will be loaded again at next boot even though they are blacklisted. Therefore we need to create a service which shuts down the NVIDIA card at shutdown. Create the following file:

    /etc/systemd/system/disable-nvidia-on-shutdown.service

    [Unit]
    Description=Disables Nvidia GPU on OS shutdown
    [Service]
    Type=oneshot
    RemainAfterExit=true
    ExecStart=/bin/true
    ExecStop=/bin/bash -c "mv /etc/modprobe.d/disable-nvidia.conf.disable /etc/modprobe.d/disable-nvidia.conf || true"
    [Install]
    WantedBy=multi-user.target

- Finally we need to do a daemon-reload and enable `disable-nvidia-on-shutdown.service`.

- Reboot

After rebooting, doublecheck that the nvidia module is not loaded:

    $ lsmod | grep nvidia

Now you can enable the NVIDIA card by running the aforementioned script `enableGPU.sh`. The script will verify if the NVIDIA card is enabled. Finally you can run a command with prime-run:

    $ glxinfo | grep "OpenGL renderer"

    OpenGL renderer string: Mesa DRI Intel(R) UHD Graphics 630 (Coffeelake 3x8 GT2)

    $ prime-run glxinfo | grep "OpenGL renderer"

    OpenGL renderer string: GeForce GTX 1050 Ti with Max-Q Design/PCIe/SSE2

Disable the card with `disableGPU.sh` to lower the power consumption.

### Troubleshooting

#### xbacklight

To get xbacklight working and not conflicting with NVIDIA Optimus:

    /etc/X11/xorg.conf.d/20-intel.conf

    Section "Device"
    	Identifier  "Intel Graphics"
            Driver      "intel"
            Option      "Backlight"  "intel_backlight"
    EndSection

#### NVRM: Failed to enable MSI; falling back to PCIe virtual-wire interrupts

Sometimes it happens after suspend/resume. GPU could work fine without MSI [3]. You could disable MSI by adding the following in `/etc/modprobe.d/nvidia.conf`:

    options nvidia NVreg_EnableMSI=0

#### Lock-ups when resuming from suspend with nvidia module

If your system locks up every time you resume from suspend with the following two lines in the output of dmesg:

    [   42.447364] pci 0000:01:00.0: Refused to change power state, currently in D3
    [   46.896493] pci 0000:01:00.0: Refused to change power state, currently in D3

You need to add the following to your kernel command line:

    nouveau.blacklist=0 acpi_osi=! acpi_osi=\"Windows 2015\" mem_sleep_default=deep

See NVIDIA bug number: 2589324, dell resolution.

## Wi-Fi and Bluetooth

These work well out of the box but you might need to update the firmware for better stability. For Bluetooth, make sure you have everything installed as per the Bluetooth wiki page.

### Troubleshooting

#### ath10k module crashes after suspend

You may notice driver crashes after suspend/resume, which for the most part does not seem to impact the running system, with coredumps similar to:

#### Wi-Fi partially looses network connectivity every 1-2 hours

With some Wi-Fi routers, the network connection might get partially lost without any noticeable change in the network status. Existing connections (e.g. ssh sessions, Zoom video calls) keep working, but loading new web pages or even pinging the gateway do not work anymore. Restarting the network fixes the problem, which however reappears after 1-2 ours.

The issue can be fixed definitively by downgrading the Wi-Fi card firmware as explained in post #17 of this forum thread. To avoid repeating the downgrade every time linux-firmware is upgraded, see pacman#Skip files from being installed to system.

#### Bluetooth disappears (after suspend?)

Possibly related to the previous instability issue, sometimes the adapter seems to completely disappear. As reported here (thanks w.v.w., you can likely fix this by manually upgrading the firmware (to something newer than what is in linux-firmware:

1. Double check adapter (e.g. QCA6174, below)

    $ lspci | grep Network

    3b:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)

2. Confirm hardware and current firmware version (e.g. hw3.2, firmware RM.4.4.1.c3-00013-QCARMSWPZ-1, below)

    # journalctl -b --grep='ath10k.*(firmware|qca)'

    kernel: ath10k_pci 0000:3b:00.0: qca6174 hw3.2 target 0x05030000 chip_id 0x00340aff sub 1a56:1535
    kernel: ath10k_pci 0000:3b:00.0: firmware ver RM.4.4.1.c3-00013-QCARMSWPZ-1 api 6 features wowlan,ignore-otp,no-4addr-pad,raw-mode,mfp crc32 fc0096a8

3. Follow the instructions at https://wireless.wiki.kernel.org/en/users/Drivers/ath10k/firmware[dead link 2024-10-12—HTTP 404]

e.g. for the above adapter, download the latest firmware from https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174/hw3.0[dead link 2024-07-30—HTTP 404] and

    $ cd /lib/firmware/ath10k/QCA6174/hw3.0
    # cp firmware-6.bin firmware-6.bin.bak
    # cp ~/Downloads/firmware-6.bin_RM.4.4.1.c3-00013-QCARMSWPZ-1 firmware-6.bin

Either `rmmod ath10k_core ath10k_pci && modprobe ath10k_pci` (as the root user) (may not work, check dmesg) or reboot.

#### ath10k-fixer

A possible workaround for some of the above issues is to reload the `ath10k_pci` kernel module when it crashes:

    # modprobe -r ath10k_pci && modprobe ath10k_pci

This workaround is automated by the ath10k-fixerAUR daemon.

## Thunderbolt docks

### TB16

TB16 works fine if either Thunderbolt security is disabled in the BIOS or using bolt to temporarily authorize or permanently enroll Thunderbolt devices with Thunderbolt security activated. Various quirks are detailed on the Dell TB16 page.

### Caldigit TS3 Plus

The TS3 Plus works fine if either Thunderbolt security is disabled in the BIOS or using bolt to temporarily authorize or permanently enroll Thunderbolt devices with Thunderbolt security activated. There is an issue where the USB ports will not work if unplugged and then plugged in again. This can be fixed by rebooting into the UEFI and using BIOS assisted enumeration (NOT native nor auto-switch), you may need to disable auto-switch, apply, then choose BIOS assisted, then apply again.

## Thermal management

Thermal design is poor in the 9570, primarily due to higher-end chips being used inside the original system design without compensating for extra heat. This impacts numerous areas:

1. Performance: at higher temperatures, CPU cores are throttled down to avoid damage. At best your system will not run as fast as it can, and at worst (and quite commonly), slower than cheaper chips and with sluggish performance.
2. Battery life is unnecessarily decreased.
3. System longevity: running at constantly high temperatures will negatively impact equipment lifetime.
4. User discomfort: uncomfortable heat and uncomfortable fan noise.

Fortunately these can all be improved significantly to get your system running powerfully and quietly.

### Diagnosis

You probably have a lot of dmesg output like this (for all CPUs), even with fairly light usage:

    kernel: CPU8: Package temperature above threshold, cpu clock throttled (total events = 8451)
    kernel: CPU8: Package temperature/speed normal

Use lm_sensors and do some stress testing (with `stress` and `mprime`) to see what is happening with CPU core temperatures and fanspeed under different loads.

### Undervolting

See Undervolting CPU on the wiki. Reduces heat and extends battery life.

Warning Versions 1.16.0 and newer of the BIOS interfere with undervolting. See this issue for more information and potential workarounds.

Possible configurations for `/etc/intel-undervolt.conf`:

1. i9-8950HK* (last updated 2019-03-30)

    undervolt 0 'CPU' -140
    undervolt 1 'GPU' -75

    * Tested extensively for moderate use.  Was not stress tested for > 24 hours.  Anecdotal reports of up to -200.

This has a more minor impact than repasting but is significantly easier to do.

### Repasting & padding

Significant improvements are possible by replacing the thermal grease used by Dell with better options available from Amazon, and adding some extra thermal padding. This might sound overwhelming but is well worth the effort, especially for newer CPUs. If you cannot do this yourself consider finding a shop / technician who can do this for you. See the following article as the user comments below it for more info:

- UltraBookReview: How to Fix Throttling on the Dell XPS 15 9570 / 9560
- Picture of 9570 VRMs - from comments of the above article

### Results

According to the author of the UltraBookReview article above:

  Undervolting seems to reduce temps at max load by 7-10C, while repasting seems to reduce temps by between 4-10C depending on your original paste job and paste used.

From this forum post, much lower/softer fan speeds were needed to maintain the same temperatures, and temperature was a few degrees lower under similar loads. Fans were on less often and for less time when they were. Throttling was less prevalent and less severe.

## Fingerprint reader

The fingerprint reader lacks Linux drivers.

Goodix will not provide them directly as stated on their forum and frequently blames the responsibility on device manufacturers.

Nonetheless Goodix stated (2020-04-30) that they are collaborating with Dell to provide the support for Linux in the second half of 2020 for the XPS 9570.

There are also some people working on reverse engineering the driver.
