[Bug 2084191] Re: [X1E] Request: Add support for Lenovo Yoga Slim 7x

Thu Mar 5 08:39:42 UTC 2026

Reading the snd-soc-x1e80100.i_accept_the_danger=1 fixed the sound issue. 
I patched 6.19.0-12-qcom-x1e
uname -a
Linux will-Yoga-Slim-7-14Q8X9 6.19.0-12-qcom-x1e #12 SMP PREEMPT_DYNAMIC Wed Mar  4 18:26:44 UTC 2026 aarch64 GNU/Linux
with the attached patch from this page:
https://bugs.launchpad.net/ubuntu-concept/+bug/2084191/+attachment/5830837/+files/0001-arm64-dts-qcom-x1e80100-hp-x14-Remove-the-additional.patch

And recompiled the kernel.
The camera works when the patch is applied:
sudo i2cdetect -y 1 (sudo apt install i2c-tools)
Show UU and qcam binary works to display the camera correctly
gnome-snapshot also displays the camera correctly.

cam -l (reports errors nonblocking though but list the camera as available)

Unfortunately enabling pipewire in firefox did not work for me for google meets (you need to set pipewire for camera to false; In firefox address bar about:config property media.webrtc.camera.allow-pipewire=false). I ended up using v4l2loopback.ko (sudo apt install v4l2loopback-dkms).
sudo modprobe -r v4l2loopback
sudo modprobe v4l2loopback exclusive_caps=1 card_label="Virtual Camera" video_nr=33
gst-launch-1.0 libcamerasrc !     queue leaky=2 !     videoconvert !     video/x-raw,width=1280,height=720,format=I420,framerate=30/1 !     queue leaky=2 !     v4l2sink device=/dev/video33
(Coverted to 720p due to starvation issues running at 1080p)
Camera works in VLC Capture Device /dev/video33

Above could be made into service script if needed for v4l interface to
camera
