Dell Latitude 7400 Ubuntu 20.04.2 (with dual-boot)
apt upgrade, my laptop froze.
Then I manually stopped it and rebooted it.
Now when I boot I find a black screen with the follow errors:
[ 4.....] Bluetooth: hci0: command 0xfc09 tx timeout [ 12.....] Bluetooth: hci0: Failed to send firmware data (-110) [ 12.....] Bluetooth: hci0: sending frame failed (-19)
I can log in with ctrl+alt+f2 but don't know what to do then ?
