On 20.04, if I open Settings > Bluetooth, the toggle sometimes kind of works, but bluetooth appears to remain off. See screenshots below.
rfkill list
seems ok:
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
I tried the plausible answers here but no luck.
systemctl bluetooth restart
seems to restart Bluetooth. – Enterprise May 15 '21 at 04:13
