And bluetooth does not work. In fact it looks like ubuntu does not recognize bluetooth HW at all. But the system does have bluetooth module which under windows is recognized as RTK8723 (ACPI\RTK8723\some-id) At the same time WiFi works without issues (the same module, if I am not mistaken). $ lsb_release -d Description: Ubuntu 20.04 LTS $ uname -vr 5.4.0-26-generic #30-Ubuntu SMP Mon Apr 20 16:58:30 UTC 2020 $ dmesg | grep -i 8723 [ 8.087918] r8723bs: module is from the staging directory, the quality is unknown, you have been warned.
