Patches for supporting Asus Zenbook A14 2025, models UX3407QA, UX3407RA.

As changes will be merged upstream, redundant patches will be dropped from this repo, to only maitain diff on top of latest linux-next.

Test setup

Kernel

  • linux-next
  • current patchset tested on next-20250522

Initramfs

  • Ubuntu's auto-built from kernel installation

HW configurations tested

  • UX3407QA
  • x1-26-100
  • 1920x1200 OLED non-touch 60Hz
  • 32GB RAM

Feature Matrix

  • WIP - Something I am already working on
  • TBH - Something I could work on, but not started / no sufficient progress was made
  • QC - Something I cannot work on, depends on Qualcomm's upstream support
Feature Status Notes
Battery Charging ✅
Battery Info ✅
Bluetooth ✅
Camera WIP Works on top of Bryan/Linaro tree. Video is upside down. ov02c10 needs to gain vflip/hflip support
Display ✅ Tested low-res OLED panel
GPU Acceleration ✅
Keyboard ✅
Microphone ✅
NVMe ✅
Speakers ✅ Require userland configuration, see below.
Audio Jack ✅
Suspend ✅ Suspends well, lid switch working. Power drop in sleep isn't best, depends on X1E generic support.
Touchpad ✅
TPM ❌ Firmware TPM
USB-A 3.0 ✅
USB-C 3.0 ✅
USB-C Booting ✅
USB-C DP Alt Mode ✅
USB-C DP over dock ✅ Series on the lists, not yet merged
HDMI WIP Parade PS185PDF DP1.4a to HDMI IC
Wi-Fi ✅ UX3407RA with FastConnect 7800 should work oob. UX3407QA requires firmware extraction and patching.
EC ❌ Similar to out-of-tree EC driver for Lenovo Slim 7x.

WCN688x WiFi

Lower-end UX3407QA has WCN6885 WiFi 6E, as opposed to WiFi 7 on UX3407RA. At least the WCN6885 is known not to work as is, as it requires both newer firmware, and patched boards-2.bin. Without these changes, driver would fail to load:

Audio configuration

Besides device tree changes in kernel, two things are required to get audio working: alsa configuration and toplogy firmware.

Audioreach-topology

cmake .
cmake --build .
  • Install compiled binary to firmware path via
sudo cp qcom/x1e80100/ASUSTeK/zenbook-a14/X1E80100-ASUS-Zenbook-A14-tplg.bin /lib/firmware/updates/qcom/x1e80100/X1E80100-ASUS-Zenbook-A14-tplg.bin

Alsa configuration

Reboot to apply changes. You should now have:

  • Working x2 speakers
  • Working x2 microphones
  • Working audio jack with microphone

Audio over HDMI and USB Type-C DP alt mode is not yet supported.

Camera configuration

The camera requires libcamera to function, and can be tested with qcam (part of libcamera-tools). However, for it to work with user-space app including browser, it must be accessible via pipewire. Sample output:

$ wpctl status
PipeWire 'pipewire-0' [1.2.7, ...]
...
Video
 ├─ Devices:
 │      51. Qualcomm Camera Subsystem           [v4l2]

 ├─ Sinks:

 ├─ Sources:
 │  *   53. Built-in Front Camera
...

Notice libcamera entry. This means pipewire recognized the camera, and it can be now used. You may skip to Userland support section.

Otheriwse, if qcam is working, but pipewire does not detect it, you need to build libcamera and pipewire from source. It was reported that everything worked out of the box on Arch, but required below manual steps on Ubuntu Concept 25.04.

Build & Install libcamera

First, remove currently installed libcamera (if any), to prevent conflicts:

sudo apt remove libcamera-dev libcamera0.4 libcamera-tools
sudo apt purge libcamera-dev libcamera0.4 libcamera-tools
sudo apt autoremove

Install dependencies for the local build:

sudo apt install git qt6-base-dev qt6-base-dev-tools libqt6opengl6-dev libjpeg-dev python3-jinja2

Clone & build:

git clone https://git.libcamera.org/libcamera/libcamera.git
cd libcamera

rm -rf build
meson setup build --prefix=/usr -Dpipelines=all -Dqcam=enabled
ninja -C build

Install:

sudo ninja -C build install
sudo ldconfig

Running qcam will now show a new version in the window title (0.5.1 as of today).

Build & Install Pipewire

Install dependencies for the local build:

sudo apt install git libboost-filesystem1.83.0  libboost-log1.83.0  liblttng-ust-common1t64  liblttng-ust-ctl5t64  liblttng-ust1t64  libpisp-common  libpisp1 libdbus-glib-1-dev libv4l-dev libudev-dev libjpeg-dev libepoxy-dev

Clone & build. It appears pipewire it tightly tied to the desktop environemnt (at least on Ubuntu), and attempt to remove it breaks things. Do not remove local installation, but do a dirty install of local binaries on top. Because of this, make to sure to not use the latest version, but the same version as installed on your host (eg. for Ubuntu Concept 25.04 its 1.2.7 as of today):

# IMPORTANT: Make sure to checkout same tag as currently installed on your host
git clone https://gitlab.freedesktop.org/pipewire/pipewire.git -b 1.2.7
cd pipewire

rm -rf build
meson build/ --prefix=/usr --buildtype=release -Dv4l2=enabled -Dlibcamera=enabled
ninja -C build/

Install:

sudo ninja -C build/ install
sudo ldconfig

Userland support

Once installed everything, reboot, or otherwise restart required services:

systemctl --user restart pipewire pipewire-pulse wireplumber

Generic apps like Gnome's 'Camera' should now work.

Firefox support

In firefox navigate to "about:config" and look for the option 'media.webrtc.camera.allow-pipewire', set it to 'True', restart the browser (all windows).
