Dell Latitude 7400 Ubuntu 20.04.2 (with dual-boot)

After an 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 ?

For those concerned, in my case, the error when mount /home partition caused this error.

  • check the error (optional)
tail -n 100 /var/log/boot.log
  • check mounted list (optional)
df -h
  • fix /home partition and then reboot
fsck -t ext4 -r /home
