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.)
