Audio

speaker / headphone are working with linux-x13s if you have:

  • pacman -S alsa-ucm-conf
  • pacman -S linux-firmware linux-firmware-qcom

mic still not working

Bluetooth

working as of kernel 6.2.0-rc7, install firmware and set an address with btmgmt. e.g., sudo btmgmt public-addr F4:A8:0D:30:A3:47

To make it just work, copy this file to /etc/systemd/system/bluetooth.service.d/override.conf (It is courteous to use your own public-addr, put a random string of numbers to make it unique.)

[Service]
ExecStartPre=/bin/bash -c 'sleep 5 && yes | btmgmt public-addr 00:24:81:17:62:36'
# Blank ExecStart line to clear the service file, overrides are additive.
ExecStart=
ExecStart=/usr/lib/bluetooth/bluetoothd

There is an open issue in bluez: https://github.com/bluez/bluez/issues/1319

A workaround may be to downgrade to 5.82-1.

Full disk encryption

These modules need to be added into /etc/mkinitcpio.conf

WWAN / 5G

This should work, you need to:

  • Ensure WWAN is enabled in the kernel config
  • Ensure linux can find your device lspci -nn | grep Foxconn should return something like: 0004:01:00.0 Wireless controller [0d40]: Foxconn International, Inc. T99W175 5G Modem [Snapdragon X55] [105b:e0c3]
  • Ensure the fcc unlock symlink in /etc/ModemManager/fcc-unlock.d matches your device, so mine would look like 105b:e0c3: symbolic link to /usr/share/ModemManager/fcc-unlock.available.d/105b:e0c3 but yours might look different depending on your lspci output.
  • Ensure ModemManager is enabled and that the access point is configured like how it is in Windows. Further reading: https://wiki.archlinux.org/title/Mobile_broadband_modem
