Ich verwende ein ThinkPad 13 Gen 2 und Bluetooth lässt sich nicht einschalten. Sobald ich Bluetooth in den Einstellungen umschalte, funktioniert es. Wenn ich dann den Bildschirm wechsle und zurückkomme, ist es ausgeschaltet. Das ist das Ergebnis vonlspci -nnk | grep -iA3 net; lsusb; rfkill list; uname -r; dmesg | egrep -i 'blue|firm'
