First of all, I find this community amazing. I have learned so much already from browsing the forums, and everyone seems open to helping each other.
I'm hoping you can help me with a problem, I've tried searching the forum extensively, but haven't found any solutions. I recently installed Mint Cinnamon 21 (and ran all updates from the update manager) on a late 2012 Mac Mini. Almost everything is great except for bluetooth. I'm trying to connect my Logitech K810 keyboard to it and it just doesn't work.
I go into the Bluetooth Devices tool from the menu, set my keyboard to pairing mode. Sometimes the keyboard shows up in the list, sometimes not. If it does show up, I will right click and click "Connect", which usually ends in an error:
Code: Select all
Connection Failed: org.freedesktop.DBus.Error.UnknownObject Method "Connect" with signature "" on interface "org.bluez.Device1" doesn't existSomeone on another thread said that there is something wrong with the Bluetooth Devices manager and that if you enable your Mint computer to be visible, then sometimes it will connect. This usually helps in making my computer detect the keyboard, but doesn't help it connect. One last piece of info: I encounter the same problem on a laptop that I have with Mint on it, but the keyboard works fine on computers with MacOS installed. This leads me to believe there is something wrong with the bluetooth driver or stack shipped with Mint?
I'm really grateful for any help on this issue, I love Mint and I want to be able to use my bluetooth keyboard with it!
