Common tweaks and fixes

This page contains Xiaomi Pad 6-specific fixes and tweaks.

⚠️ AT FIRST CHECK IF YOUR KERNEL NAME MATCHES MODULES DIRECTORY

Check your name kernel using uname -r and check if corresponding modules directory with the same name as kernel exist in /lib/modules. If not, you forgot to install modules. In the future this will be automated.

People often had problem on our Telegram groups because of that mismatch, they forgot to install modules and flashed another boot image.

First boot

resize2fs /dev/disk/by-label/arch_rootfs
pacman-key --init
pacman-key --populate archlinuxarm

Bluetooth

Bluetooth exist but doesn't work

This is usually caused by Bluetooth interface having no assigned MAC address.

btmgmt --index 0 public-addr <your desired mac address>.
