Hi, i got some problem with blueman-manager, so it doesn't want search for any devices, only after reboot system, then maybe it will work, but not always. All buttons are not available(except exit)

Anything in bluetoothctl list? Otherwise, your system does not have any adapter set-up.

You right. It is something in system. In my case only device byself in list.
root@wst-pc:~# bluetoothctl list
