My laptop's wireless module intel AX200, which means it should be using the iwlwifi-cc-46.ucode firmware. The mourse pairs and connects fine. However, it doesn't reconnect after reboot. Not even manually. Here is my dmesg output

Here are some methods I have tried:

  • setting UserspaceHID=true in /etc/bluetooth/input.conf
  • installing blueman to let it manage my connections but that doesn't work.
  • firmware update (I only updated one file though)

Also, I disabled secure boot. If that's relevant.
