Been running tumbleweed for about a month. So far so good, but have had Bluetooth issues since day 1. At first I thought it was my hardware but I think it’s gnome.
When I turn Bluetooth off in the top right gnome menu, the icon disappears. When I go into Bluetooth settings, the toggle switch is on even though rfkill states blocked.
This forces me to have to manually turn it on every time by going into bluetoothctl. Not a huge issue, but kind of annoying that the gnome system menu isn’t working.
Anyone else having this issue? I’m using a Dell XPS 15 9500.
I cannot help you much, but what you describe rings a bell since I witnessed something similar in the past.
Now with Gnome 40 everything seems OK here, but occasionally after switching “Airplane mode” on and off the Bluetooth controller doesn’t resume and I need to reboot to be able to switch it on again.
I also saw funny interaction between BT, WiFi and “Airplane mode” (AKA “switch off all radios”) in the past so I think that some HW dependency is at play and Gnome settings might not be able to get a clear picture of what is going on.
Hope that somebody with the same DELL model reads your post and is willing to help.
