Recently I bought a new keyboard, which I intend to use when my laptop is placed in its docking station. There are two external monitors connected, making the display of the laptop rather useless (only two outputs are supported at the same time). In normal circumstances the laptop lid will be closed, so the keyboard is not accessible.
My new keyboard is a Logitech K760 and is connected through bluetooth. Pairing with help from the the XFCE/GNOME tools is easy enough, but this causes the keyboard to be available after login only. That is not very practical. After boot, I have to login through GDM and prefer to not need to use the keyboard of the laptop itself. For this, I needed to figure out how to make the bluetooth keyboard available on system level, and not per user. Descriptions on how to do this seem to be very sparse, and mostly depend on other distributions than RHEL or Fedora. I prefer to use standard tools as much as possible, adding custom scripts for these things makes it more difficult to move configurations between systems. Furthermore the keyboard can be paired to multiple (3) systems at the same time, the F1-3 keys can be used to select a system, similar to a KVM switch.
