I have two Ubuntu machines in a closet, and a USB cable coming out from there via a Video/USB switcher. My keyboard, mouse, a tablet screen, and USB audio are all hanging off the far side of the Video/USB switcher. That all works great for wired keyboards and for a couple of wireless mice.
However if I try to use a Bluetooth mouse and keyboard, one system (running Ubuntu 18.04) works fine, but the other, running 20.04 does not.
The 20.04 machine sees the Bluetooth adapter (and using my phone I can see that machine advertising itself when I go into the Bluetooth settings page). However, the 20.04 machine won't pair with the keyboard, and doesn't even seem to see the mouse. The keyboard is capable of pairing to multiple devices, but I don't believe the mouse is.
Is this some limitation on Bluetooth? I was hoping the keyboard and mouse would pair with the USB adapter rather than with the machine behind it, but it seems that's not the case.
Can anyone tell me what I should and should not be able to make work? And does anyone else run Bluetooth keyboard / mouse to multiple machines behind a switch? If so, how do you handle this?
