No Bluetooth mouse in sddm before first login

[Andrej Podzimek]

Hello,

In Fedora 23, my Bluetooth mouse works fine in KDE. However, it doesn't work in sddm before the first user logs in. It works afterwards and keeps working even after the first (or second or whichever) user logs out.

The very first login without a mouse is quite an inconvenience. Any ideas what could be wrong? The same thing works perfectly fine in Arch -- the mouse works from the very beginning, once it's paired by a user in the KDE Bluetooth GUI, there's a bunch of metadata stored somewhere in /var about the pairing and the mouse can easily reestablish its connection, no matter if users are logged in or not.

What can be different on Fedora? SELinux? And why does the mouse magically start working as intended once the very first user logs in? Just abou tany debugging tips would be helpful. (Looking at .xsession-errors for sddm/root/user and logs from bluettothd, sddm and X.org didn't yield anything eye-opening thus far.)

Cheers,
Andrej
