The 2015 Dell XPS 13 (9343) is the second-generation model of Dell's XPS 13 line. Like its predecessor, it has official Linux support courtesy of Dell's Project Sputnik team[1]. They target Ubuntu 14.04 LTS, but the improvements and support from the Sputnik team are generally applicable to all distros.

The installation process for Arch Linux on the XPS 13 does not differ from any other PC. For installation help, please see the Installation guide and UEFI pages. This page covers the current status of hardware support on Arch, as well as post-installation recommendations.

As of kernel 4.1.3 (released July 2015), a patched kernel is no longer necessary. However, some manual configuration is still recommended to get the best experience.

## Model differences

Although the XPS 13 is sold in a variety of configurations in most markets, those wanting to run Linux should pay special attention to display options (FHD or QHD+) and Wi-Fi adapter differences (Dell DW1560 or Intel 7265).

Users with QHD+ displays should use a DE/WM that properly supports HiDPI.

Regarding the Wi-Fi adapter, both cards work in Arch Linux. If the Intel one works out-of-the-box thanks to mainline kernel support, the Dell DW1560 instead requires a proprietary kernel module that is not well-supported; further details are reported in the proper below section.

There are no exclusive hardware differences between the Developer Edition and the standard Windows edition, so this guide is equally applicable to both models.

## Configuration

### BIOS updates

Note: LVFS does not support this device, thus you cannot use fwupd in order to upgrade the BIOS. To do it, proceed manually as described below.

The latest BIOS update is A20 and it was released on 8th October 2019. With version A02 or newer, almost everything should work out-of-the-box and the kernel boot parameters that were used in conjunction with earlier BIOS versions are no longer necessary.

BIOS upgrade is easy thanks to the EFI implementation: place the update binary (the just downloaded `.exe` file) in the EFI partition (`/boot/EFI`) or on a USB flash drive, reboot, press `F12` key in order to enter in the Boot Menu and then choose BIOS Update.

### Screen and Keyboard Backlight

Backlight and its control work out-of-the-box:

- The systemd-backlight.service takes care of both eDP panel and keyboard backlight (and any other external device) status, saving at shutdown and restoring their values at boot.
- Hardware Function keys (`Fn-F11` and `Fn-F12` for screen backlight and `Fn-F10` for keyboard backlight) work without any operation, as well.

Note: By default, the keyboard backlight automatically turns off after 60 seconds of inactivity. You can change the default behaviour by editing the related sysfs entry `/sys/devices/platform/dell-laptop/leds/dell\:\:kbd_backlight/stop_timeout`.

#### Dynamic Backlight/Brightness Control (DBC)

You may notice that the screen looks dimmer than you expect or the screen overall brightness changes constantly. This behaviour is not a symptom of any monitor issue but a technology called Dynamic Backlight/Brightness Control (DBC), designed to save energy according to the content displayed on the screen.

Tip: You can check this feature on this website.
Warning: This feature is automatic and not-controllable. According to official Dell source, only the QHD+ models have a chance to disable it via a firmware update.

### SSD

This laptop series comes with a SSD as storage device, connected via SATA. This technology needs some configuration in order to achieve the best operative conditions. See Solid State Drives for further information.

### Wi-Fi

Most configurations sport the Dell DW1560 802.11ac adapter. This is based on the Broadcom BCM4352 chip which requires proprietary driver to work. Packages broadcom-wl and broadcom-wl-dkms provide it. In the former case remember to install the Linux kernel headers too (even if it is listed as an optional dependency of the dkms package, it is mandatory for having a working network). See the Broadcom wireless page for more details and/or assistance.

Some higher-end models do not use the above-mentioned adapter, instead they use an Intel Wireless 7265 card which is supported by the mainline kernel.

Note: The Intel card is widely available as an after-market purchase for those wishing to replace the Broadcom adapter in their laptop. This option, other than an enviable driver support for both Wi-Fi and Bluetooth that makes installation easier, compared to the Broadcom card, it has a 2-3 times wider reception range and a much higher throughput, making it a worthwhile upgrade. Other cards are also available, especially the Intel Wireless 8265 is known to work[2].

### Bluetooth

Note: For users with Intel wireless adapter with both Wi-Fi and Bluetooth, the Bluetooth interface should be available out-of-the-box, as the required firmware is included in linux-firmware.

The Broadcom Bluetooth firmware is not available in the kernel (source), so you need to install bcm20702a1-firmwareAUR and reboot if you want to use Bluetooth.

Alternatively, you can retrieve the firmware directly from the Windows driver by yourself. You need to extract the `.cab` file with cabextract and then convert it to a `.hcd` file with hex2hcd from bluez-utils:

    $ cabextract 20662520_6c535fbfa9dca0d07ab069e8918896086e2af0a7.cab
    $ hex2hcd BCM20702A1_001.002.014.1443.1572.hex
    # mv BCM20702A1_001.002.014.1443.1572.hcd /lib/firmware/brcm/BCM20702A1-0a5c-216f.hcd
    # ln -rs /lib/firmware/brcm/BCM20702A1-0a5c-216f.hcd /lib/firmware/brcm/BCM20702A0-0a5c-216f.hcd

After reboot, the firmware is available for your Bluetooth interface.

### Audio

Note: Proper audio support is dependent on having the latest BIOS update. If you have not yet updated to BIOS A02 or newer, please perform #BIOS updates first.

The sound chipset in this laptop, a Realtek ALC3263, is described as "dual-mode", meaning it supports both the HDA standard and the I2S standard. The embedded controller in the XPS 13 uses the ACPI _REV value provided by the OS itself to determine in which mode the sound chipset should be initialized in at boot.

#### HDA mode

With BIOS A02+ and official Arch Linux kernels older than 4.4 and again starting from version 4.11.5, the sound card will be initialized in HDA mode.

Note: To use HDA mode on excluded kernels, re-compile them with the option `CONFIG_ACPI_REV_OVERRIDE_POSSIBLE=y`. This will force HDA mode on.

##### Setting the default sound card

By default, ALSA does not output sound to the PCH card but to the HDMI card. This can be changed by following ALSA#Set the default sound card. To set the proper order, create the following `.conf` file in `/etc/modprobe.d/` [3]:

    /etc/modprobe.d/alsa-base.conf

    options snd_hda_intel index=1,0

Note: If you are dual-booting with Windows, you will have to do a cold boot twice before to have sound working in Linux and vice-versa.
Note: This is not necessary in I2S mode.

#### I2S mode

With BIOS A02+ and official Arch Linux kernels from 4.4 to 4.11.4, the sound card will be initialized in I2S mode. I2S support requires alsa-lib 1.1.0[4] or newer. (I2S support was broken in mainline kernel 4.5, and fixed in Arch kernel 4.5.2 and mainline 4.8FS#48936[5]).

##### Enabling the microphone

Note: The microphone appears to be enabled by default as of official Arch Linux kernel 4.5.3, so these instructions may be unnecessary FS#47989#comment146876.

In I2S mode, the built-in microphone is muted by default. To enable it you have to unmute the `Mic` item. Follow the instructions below in order to achieve the goal:

- open `alsamixer` (an utility included in the alsa-utils package)
- press `F6` and select the broadwell-rt286 sound card
- press `F4` to switch to the Capture view and ensure that ADC0 has the CAPTURE label. If it does not, toggle over to it with your arrow keys and press the spacebar to turn it on CAPTURE
- finally, toggle over to the Mic item and raise the volume to 100.

Note: Cycling the Port (from Main Microphone to Headset Microphone (unplugged), and back) of the Input Devices tab in the `pavucontrol` application, has the same effect of the above instructions.

##### Using Jack

By default Jack recognises four capture ports and is unusable because the transport is broken into short fragments with breaks between them. Limit input to two channels with `-i2` on the command line or the corresponding option in qjackctl's advanced settings.

### Touchpad

With the latest BIOS, the touchpad should work out-of-the-box with either the synaptics or libinput drivers. The second is recommended over the former.

#### Synaptics driver

For more advanced settings with the Synaptics driver, see Touchpad Synaptics.

If the touchpad freezes when you use more than one finger, try enabling Clickpad mode with `synclient Clickpad=1`.

#### Libinput driver

For better multi-touch support, you can use xf86-input-libinput. The libinput driver supports nearly all button layouts out-of-the-box with few additional settings.

Refer to the specific libinput page for more details.

For further configurable options (e.g. NaturalScrolling, MiddleEmulation), see libinput(1).

### Powersaving

With kernel 4.6.5 and tlp, the idle power usage can reach ~2.3 W with the kernel parameter `pcie_aspm=force` enabled.

You may use powertop or powerstat-gitAUR to reproduce and check this behaviour by yourself.

Note:

- With kernel 4.6+, frame-buffer compression (FBC) is enabled by default, so `i915.enable_fbc` is no longer needed.
- Panel self refresh (PSR) causes the display to flicker, so it has been disabled by default as of kernel 4.9 [6].
- `i915.lvds_downclock=1` for LVDS downclock is no longer needed. According to IRC #intel-gfx, "[...] there is a new auto-downclock for eDP panels in recent kernels and it is enabled by default if available, [...]".
- `i915.enable_rc6=7` is useless on Broadwell (Gen8) systems because the deeper GPU power states that this option enables (RC6p and RC6pp) do not exist on Gen7+ hardware [7][8].

### Calibrated ICC profile

#### QHD+ model

Warning: This profile is only for QHD+ model. Do not use it if you have the FHD one.

An ICC profile is a binary file which contains precise data regarding the colour attributes of the monitor. It allows you to produce consistent and repeatable results for graphic and document. The following ICC profile is made with dispcalGUI ( displaycal) ArgyllCMS ( argyllcms) and a spectrophotometer for absolute colour accuracy; even if it is possible to achieve better results by calibrating your own monitor by yourself, in general this profile is definitively an improvement over the stock profile.

This profile has been made with the spectrophotometer's high resolution spectral mode, with white and black level drift compensation, the high quality ArgyllCMS switch and 3440 patches. Dynamic Brightness Control has been disabled and the monitor has been turned on for at least 30 minutes prior to start the calibration.

- QHD+, D65, Gamma 2.2, max luminance.

### Disable the touchscreen

This is an optional step and was tested 07.2019 using Gnome and Wayland. Find out which device it is:

    libinput list-devices

Scroll to find the right section (Something like ELAN Touchscreen) and find the line "Kernel: /dev/input/event#". (in my case 6) Use the event# for the next command:

    udevadm info -a -p /sys/class/input/event#

Find an attribute that is most probably unique/distinct. (I used: ATTRS{name}=="ELAN Touchscreen" ) Use this in a newly created file: /etc/udev/rules.d/99-disable_touchscreen.rules

    KERNEL=="event*", ATTRS{name}=="ELAN Touchscreen", ENV{LIBINPUT_IGNORE_DEVICE}="1"

Then check if it worked:

    udevadm test /sys/class/input/event6

and search for:

    LIBINPUT_IGNORE_DEVICE=1

If this line is there (most probably within the last 3 lines) reboot and your touchscreen should be disabled.

## Troubleshooting

### EFISTUB does not boot

Update the BIOS. In more recent versions (A19 at the latest) it works. Older versions of the BIOS do not pass any boot parameters to the kernel and you have to use a UEFI boot loader instead. systemd-boot will work with current kernels. Alternatively, packaging the command line, microcode and initramfs with the kernel into a single EFI will also work. This can then be added as an entry into the boot manager. See this example, doing so using `objcopy`. Similarly, creating a signed EFI using cryptbootAUR and sbupdate-gitAUR will also work.

### Random kernel hangs at boot

See here. This issue seems to affect only touchscreen model owners. The fix consists in removing "keyboard" from the HOOKS array in /etc/mkinitcpio.conf. If you need the keyboard at boot, edit the MODULES array as follow MODULES="atkbd usbhid hid-generic". You will have to run `mkinitcpio -p linux` as root afterwards.

### Sometimes the system fails to resume from suspend after closing and reopening the LID

Even if it has been reported as fixed upstream according to this kernel.org bug report, users still suffer of this problem (reported for both FullHD model with kernel 4.20.12 and the QHD+ model with kernel 4.18.6).

One more, following a comment in the abovementioned bug report, you can work it around by blacklisting mei modules:

    cat << EOF | sudo tee /etc/modprobe.d/blacklist.suspend-bug.conf

    blacklist mei
    blacklist mei_me
    EOF

### Graphical artifacting/instability after S3 resume

If you encounter some artifacts and/or an unusable graphical environment after resuming from a suspend, you may want to switch your Intel graphics acceleration from SNA to UXA. Switching to UXA, however, will result in worse performance. Switching to xf86-video-modesetting (Glamor acceleration) should not decrease performance considerably,however it is still not known if will fix the resume issue.

### Connection issues with Broadcom wireless

If `wifi-menu` and `iwlist scan` fail after driver installation and reboot, try disabling "Wireless Switch" control in the BIOS.

### Wireless switch/rfkill issues with KDE

As from kernel version 4.4 the rfkill switch works. The KDE plasma-nm (NetworkManager) widget does not indicate that wlan is active after it has been reactivated, but still connects correctly. The KDE system tray bluetooth widget usually disappears if the switch disables bluetooth, and fails to reappear when it is reactivated. You can work around this by setting the switch not to switch bluetooth in the BIOS setup. With kernel version < 4.13.11 and/or plasma-desktop < 5.11 the mouse pointer may freeze first time that the rfkill switch is used. To unfreeze it, switch to another virtual console and back.

### DE cannot connect Bluetooth devices

If the Bluetooth GUI cannot connect the device, try to use `bluetoothctl` to connect manually.

### Sound does not work after upgrading to kernel 4.4+

You need to do two cold boots (NOT a simple reboot, shut it down and turn it back on again) to make sound working again.

Refer to the #HDA mode above for more info, as well as the BBS thread and Arch Linux bug report.

### Loud cracks/noise during boot or audio playback

Some users have reported the above sound problems, as described here for example.

Disabling audio powersafe may work for people using the HDA audio mode.

However, it is still unknown how to solve this issue for the I2S audio mode.

For further reference, see the corresponding kernel bug entry.

### Pink & green artifacts in video or webcam output

Update xf86-video-intel to latest version. This should fix the issue.
