No idea WTF happened but after a regular reboot Bluetooth is just gone. Settings says ‘no Bluetooth adapters installed’.
I have an HP Bluetooth mouse that can connect both via Bluetooth as well as its provided USB dongle - I’ve switched to using the latter for now.
How do I fix this?
systemctl status bluetooth
bluetooth.service - Bluetooth service
Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; preset: enabled)
Active: inactive (dead)
Docs: man:bluetoothd(8)

See if it shows up when lsusb
is run in a terminal. It should, even if non-functioning.
The Bluetooth, unless run from an external dongle, is most likely a chip included on the internal wifi card. Is your WiFi working correctly?
Even though the wireless card may be a PCI connection, the bluetooth is using internal USB, so lsusb
is where you will find it.
If there had been a recent kernel update, I’d suggest booting to a previous entry. It still might be worth a try, even if just to rule it out.
If you have Windows fast-startup enabled, this can lock hardware.
Check if your BIOS settings have a fast boot mode enabled. This skips some hardware checks, and might be a cause.
Some reports mention a cold boot, even unplugging the power and holding the power button for a bit to force the mainboard to reinitialize and recheck the hardware.

I had this happen to me. Turns out it wasn’t a neon issue but one with my bother board (Asus Tuf Gaming). I needed to shut down my computer, turn off the PSU and hold in the start button for 10 seconds. After that I switched back on the PSU and booted my machine and it worked.

It’s back now. No idea again why.
