Audio
Audio (both speakers and microphone) works out of the box with
Sound Open Firmware
.
alsa-utils
might also be required for the built-in microphone to work and the microphone mute key indicator LED to sync correctly.
Some users have reported issues with the microphone that were often fixable by running as follows:
# alsactl init
# alsactl store
Webcam
Works, but with proprietary userland, and workarounds needed to make use of it as a webcam in browsers. Some effort to get it working was listed
here
.
Programs that make use of
PipeWire
for video recording should work in kernels released after 6.10 after installing
intel-ivsc-firmware
AUR
,
libcamera
and
pipewire-libcamera
.
Firmware
Dell provides firmware updates that can be installed automatically using
fwupd
.
It is possible to install custom
Secure Boot
root keys in the BIOS and use them for Secure Boot with Linux. The system is able to boot even with no Microsoft keys enrolled.
Function keys
The function keys is a backlit capacitive touch panel on this laptop model - a touchbar where you, by pressing the Fn key, can switch between either the traditional F1-F12 row, or a function key row. The default mode can be selected in the BIOS.

Backlight
The backlight level of the touchbar is not controllable from software - it is set by the light sensor hardware built-in to the laptop. If you think the backlight level is too severe, you can force it to stay in the lowest setting by blacklisting the kernel modules responsible for initializing the backlight sensor:
/etc/modprobe.d/touchbar.conf
blacklist intel_ishtp_hid
blacklist intel_ishtp
blacklist intel_ish_ipc
Accessibility
Note
Blind users should request the help of a sighted person to change firmware settings.
BIOS Settings Overview
The "BIOS Settings" interface can be reached by pressing
F2
during POST.
The BIOS settings page itself is GUI based, with black text on a white background. There is a panel taking approximately 20% of the screen on the left, containing various sub-categories of settings. The main panel takes 80% of the screen to the right, and contains the settings associated with each sub-category. The font is relatively large, and toggle switches will appear as light grey if set to 'off', and turn light blue if set to 'on'.
The GUI does not have any built-in screen reader or other accessibility settings, but due to its simple colour scheme, and relatively large text size, it should be somewhat accessible for partially sighted people using an external screen reader as an accessibility aid. However, it is a GUI-based interface with lots of available settings, and lots of visual clutter in text form. As such it is likely to be difficult to navigate for people with severe visual impairment or total blindness, who are using an external reader alone. It is possible to enable/disable "Help Text", and "Advanced Setup" using two toggle switches that appear in the top left corner of the screen; disabling them should help reduce this clutter and improve readability (but may also hide useful info/settings!).
There are "Show all" and "Search" functions available towards the top right of the screen, which can ease navigation considerably.
The BIOS can be updated through the "One-Time Boot Menu" (press
F12
during POST).
BIOS Settings Navigation
The "BIOS Settings" interface can be navigated using a keyboard, or mouse - with mouse being the preferred mode. Keyboard navigation keys are as follows:
Key
Effect
Up
Moves to the previous field.
Down
Moves to the next field.
Enter
Selects a value in the selected field (if applicable) or follow the link in the field.
Space
Expands or collapses a drop-down list, if applicable.
Tab
Moves to the next focus area
PageUp
Scrolls the currently selected view up.
PageDown
Scrolls the currently selected view down.
Esc
Moves to the previous page until you view the main screen. Pressing Esc in the main screen displays a message that prompts you to save any unsaved changes and restarts the system.
Diagnostics
Pressing
F12
during POST starts the "One-Time Boot Menu" (if enabled in BIOS). There the diagnostic option can be found, which offers various thorough on-board tests.
If
d
is held while powering on, the "Display panel built-in self-test" (LCD-BIST) is initiated. The screen will cycle three times through solid colors before powering off again. This can be used to make sure all colors are displayed correctly without distortions and no dead pixels are present.
The "Service LED" is located just above the
F6
and
F7
function keys. It can emit white and amber light. Usually it shows the current power and battery state, but blinking can indicate an issue with the computer has been detected. Diagnostic codes for the blinking pattern can be found in the official service manual linked at the end of this article.
