Dear all; I had the same issue with Kubuntu 20.04LTS, yesterday and during the installation the bluetooth was working perfectly on my Asus UX305ua than, this morning, no bluetooth adapter found. I solved it by simply plugin in (power supply) my laptop. It appear to be an issue with the power management (energy saving). Something disable the bluetooth adapter to save energy.
So if you have this issue could you try to replicated the issue by 1. pluging the power cord 2. spinning an ubuntu live-cd This might help the maintainer/developer to help us :) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1523108 Title: Bluetooth doesn't work on ASUS Zenbook UX301LAA Status in linux package in Ubuntu: Triaged Bug description: It's not possible to make bluetooth work.
