Hello,
I originally posted this under “Languages > French” (my native language) but got no answer, so I’m posting it again here and translating it as best as I can.
After waking up from suspend, sometimes, my PC’s integrated Bluetooth adapter isn’t detected anymore. When opening GNOME settings, under “Bluetooth” it says : “No Bluetooth found”.
Apart from this, Bluetooth is working perfectly on my computer, even after suspending. But it seems that the adapter disappears from my system after certain randomly selected wake-up times. I have to reboot my PC to get Bluetooth back.
Here is what rfkill
gives me when Bluetooth is working :
ID TYPE DEVICE SOFT HARD
0 wlan phy0 unblocked unblocked
1 bluetooth hci0 unblocked unblocked
And here is what it gives me after waking up from suspend when the Bluetooth adapter isn’t detected anymore :
ID TYPE DEVICE SOFT HARD
0 wlan phy0 unblocked unblocked
Here are lspci
, lsusb
and inxi
outputs, in that order (these are the same when the adapter is detected as when the adapter stops being detected) :

My PC is a 2016 Dell Inspiron 3650 desktop.
I also had this problem when running Ubuntu 18.04, 20.04 and Manjaro KDE, so it doesn’t seem to be distro specific.
I copied the outputs above when running Linux 6.2, but the problem persists with Linux 5.15.
Thanks in advance !
