Bluetooth is sadly quite unreliable on Linux, I've never found it to be otherwise, so sometimes I just need to turn it off and turn it back on to make my bluetooth keyboard reconnect. For that I use the wired mouse. But now switching from something else to OpenSUSE, suddenly the bluetooth toggle on the lock screen is grayed out. Since you apparently want me to login to use it, but that would require me to toggle bluetooth, that leaves me stuck. I think the obvious fix would be to not gray out such toggles on the lock screen. I'm picking severity major since it leaves me unable to lock back in multiple days per week which is really stopping me in my tracks and there isn't really a workaround that I've found. (Other than finding a wired keyboard, so with the input devices I previously used that worked fine for me I simply can't proceed.)
