Connect keyboard before login

[jj-foren]

Hi
I have a mac mini running on LinuxMint 22.3. I managed to configure my Logitech MX Master mouse and keyboard without big trouble.
However, on startup, sometimes the mouse connects but the keyboard does not, sometimes vice versa, and sometimes both don't connect.
In case when only the keyboard connects, I can login, start blueman and it shows the mouse as known device. When I hit "Search" via the keyboard navigation the mouse is connected immediately. I have activated the "Autoconnect" option for both devices.
Obviously I cannot login without the keyboard connected, I have to shutdown and reboot and hope that keyboard is connected then.
The easiest solution or workaround for me would be to put the bluetooth system into "search"mode for the first minute or two after startup. Is this possible?
Thanks
JJ

Unfortunately for you in this scenario blueman is just a frontend which isn't running yet when you're at the login screen. So any autoconnect features you enabled are not active.

OK thanks for the reply. I understand that blueman is just a frontend. Forgive me if this is just thought too naive, but: Can the command that is triggered by hitting "search" in the GUI also be triggered by some sort of startup script during boot?
Thanks again, JJ

Sure. Your best bet is probably just bluetoothctl. You could put it in a systemd service or possibly trigger it via your display manager.
