Dell XPS late 2020 edition.
In some units, the NVMe drive is configured to operate in RAID mode by default. This may cause the bootloader to not find your boot disk. In order to fix this, press
F2 to enter the Dell UEFI. Go to Storage > NVMe Operation and make sure that Select AHCI/NVMe mode is selected. All other operating systems installed before changing this setting must be reinstalled after changing this setting.
To successfully boot the installation medium you will need to disable Secure Boot.
This laptop requires firmware in order for the soundcard to work. See Advanced Linux Sound Architecture#ALSA firmware.
There are two possible devices the laptop may ship with, AX201 or AX500. AX201 support is already in the mainline kernel
Since Kernel version 5.10.9, users have reported some success with the Arch stock Kernel (a recent Dell firmware is also required: at least version 1.2.5), however there are are persistent problems, including firmware crashes and problems when resuming from hibernate/suspend. If your wifi is not working, first try to add the following parameter to your kernel command line:
Note that if you add this in
/etc/defaults/grub, you need to enter it as:
Details about this fix can be found in the Linux kernel mailing list: https://email@example.com/. After adding this parameter there still may be problems with wifi functionality on resuming from suspend. Enabling `VT for Direct I/O` in the BIOS may help with recovering wifi functionality after a suspend. Please note that the ath11k driver is still experimental. While it is reported to working fine with a 2.4 GHz WPA Personal WiFi network, there might be problems after disconnecting the WiFi or with different setups (WPA3, 5 GHz WiFi). Your mileage may vary. However, recovery from suspend and hibernate appears to be broken, though it can usually be manually fixed by reloading the
ath11k_pci module. For example:
# rmmod ath11k_pci
wait a couple minutes (yes really) for the operation to complete
# modprobe ath11k_pci
This can be automated via sleep hooks - if the module is unloaded before hibernating or suspending it unloads immediately with no delay, and the resume kernel bug does not happen:
[Unit] Description=Suspend: rmmod ath11k_pci Before=sleep.target [Service] Type=simple ExecStart=/usr/bin/rmmod ath11k_pci [Install] WantedBy=sleep.target
[Unit] Description=Resume: modprobe ath11k_pci After=suspend.target [Service] Type=simple ExecStart=/usr/bin/modprobe ath11k_pci [Install] WantedBy=suspend.target
You need to enable
There is also work in progress in the form of qca6390 (the SoC of Killer AX500) driver development in the kernel.org kvalo/ath repository. Patches based on the ath11k-qca6390-bringup branch have been working (with an "experimental" caveat) for a while.
As of 5.16.16, bluetooth is partially working, but must be activated manually after boot is complete. You must blacklist
hci_uart by adding
blacklist hci_uart to
modprobe hci_uart after boot and start the
bluetooth service with systemd. Functionality still appears broken after resuming from suspend. Note that when
hci_uart is loaded during boot, or after suspending, the laptop may hard lock with errors similar to
watchdog: BUG: soft lockup - CPU#2 stuck for 23s! [swapper/2:0]. See the talk page for additional details.
The fingerprint sensor can be used by installing the proprietary Ubuntu driver released by Dell and Goodix. This requires a different fork of, AUR. This is a newer version intended for use only with touch-based sensors such as the one on the XPS.
The proprietary driver is available as Dell repository by extracting the Debian file and copying its contents.AUR. Alternatively, it can also be manually installed from the
The rest of the process is identical to that described on fprint—just make sure not to install the version of libfprint in the official repositories as it conflicts with libfprint-tod-git.
When the IR camera (
/dev/video2) is on, it will not automatically turn on the IR emitter. You can follow the instructions from linux-enable-ir-emitter to enable the IR emitter. This is the
IrConfig.yaml file as detected by the quick command so you do not need to go through all the manual configuration steps:
!!python/object:IrConfiguration.IrConfiguration _data: - '0x1' - '0x3' - '0x2' - '0x0' - '0x0' - '0x0' - '0x0' - '0x0' - '0x0' _selector: '0x6' _unit: '0x4' _videoPath: /dev/video2
The infrared camera can be used as an authentication method withAUR.
The configuration file is located at
/lib/security/howdy/config.ini. The device should be configured like this:
device_path = /dev/video2.

Random hangs on i915 with kernel older than 5.14
Occasionally the laptop hangs when running the i915 Linux driver. This results in an occasional visual delay to keyboard inputs and makes the system appear to be crashing.
The bug report for this issue can be found here: https://gitlab.freedesktop.org/drm/intel/-/issues/3496
Set panel self refresh to off in the kernel parameters:
i915.enable_psr=0 i915.enable_fbc=1. This is unnecessary with kernels >= 5.14.
Sleep/Modern Standby battery drain
Since 11th gen Intel CPUs do not support deep sleep (S3) anymore and modern standby drains battery life very quickly, the solution is to switch the Storage in the BIOS from RAID to AHCI and battery life will dramatically improve in (modern standby) sleep mode. This requires bcedit'ing windows in case of dualboot or windows will not boot anymore - does not affect the Linux partition though.
