My bluetooth mouse is connected now, but I had to follow a special process...
WHAT WORKS:
I had to turn OFF my wireless, make sure bluetooth was ON, and then connect/pair the mouse.
After the bluetooth mouse connected successfully, I was able to turn wi-fi ON again.
Now, my mouse automatically connects a few seconds after logging in.
It has not disconnected for the brief time I have used it, but I will post back if I notice any new issues.
WHAT DOESN'T WORK:
* I found that the previous work-around in comment #17 no longer works.
* I found that newer kernels did not work either.
NOTES ON KERNELS:
I tested mainline kernels 4.14.9 thru 4.14.15. All of these newer kernels produce the following error message during installation: "Error! Bad return status for module build on kernel". (Note: this is most likely because I have the Nvidia proprietary drivers version 384.111 installed).
However, kernel 4.14.8 installs just fine. But this did not fix the bluetooth problem, until performed the above procedure.
OTHER THINGS I TRIED:
I did execute "sudo bluetoothctl", and I tried to "trust" and "pair" my mouse from the command line, prior to performing the "wi-fi-off/wi-fi-on" process. However, I do not think "bluetoothctl" helped.
