Laptop saya, MSI GS70 Stealth Pro, telah membangun perangkat Bluetooth bawaan yang tampaknya tidak dikenali Ubuntu.
Saat saya membuka System Settings > Bluetooth katanya No Bluetooth adapters found .
Dari apa yang saya lihat di utas lain, saya meninggalkan beberapa info semoga bermanfaat di sini:

Bagaimana cara memperbaiki masalah ini?
Terkait:Perbarui GCC ke versi 6.3?Jawaban yang Diterima:
Masalah ini muncul karena Atheros menggunakan kembali chip VID dan PID.
Lihat laporan bug ini
Sebagai solusinya, Anda dapat menambal btusb.c modul dan ubah dari ath3k ke Roma.
Saya telah membuat paket DKMS untuk memperbaiki masalah ini dan mengunggahnya ke PPA saya.

Instal deb ini dan reboot. Ini akan memperbaiki masalah.
