Bluetooth keyboard and mouse not pairing properly

1 min readlinuxbluetoothgnomerealtek

Problem

My Bluetooth keyboard and mouse were not pairing properly with my laptop. Devices would show up, disconnect, or fail to respond. Spent from last night through this morning debugging it (with help from AI).

Environment

  • OS: Linux (kernel 6.17.0)
  • Desktop: GNOME (with leftover XFCE bluetooth tooling)
  • Chip: internal Realtek Bluetooth radio
  • Devices: Bluetooth keyboard + mouse

What worked

Two steps — stop conflicting services, then hard-reset the radio.

1. Stop the service conflicts

The old XFCE bluetooth manager (blueman) was fighting GNOME for control of the adapter. Remove it and restart the bluetooth service:

sudo apt remove blueman
sudo systemctl restart bluetooth

2. Unblock and reset the radio

Force-reset the internal Realtek chip to clear a hung firmware state:

sudo rfkill unblock bluetooth
sudo hciconfig hci0 down
sudo hciconfig hci0 up

After both steps, pair the keyboard and mouse again from GNOME Settings → Bluetooth.

Notes

No new hardware needed — this was a software conflict plus a stuck radio state. If it happens again, try step 2 first before reinstalling anything.
