Ubuntu 20.04.3LTS stuck on "Bluetooth: hci0: unexpected event for opcode 0xfc2f" after sleep

cn flag

Ever since I updated from 18 LTS to Ubuntu 20 LTS this has been happening 90% of the time I close my monitor lid and when I open up the lid to reactivate my computer from sleep it would be stuck on the screen in the picture below. I've tried some things I found online, unfortunately no one directly has my problem. I'm still kind of a noob to Ubuntu, so any help would be appreciated, or else I'll probably wipe and reinstall Ubuntu 18 or 20 LTS.

I am facing the same issue. Have you been able to solve it?

I solved it by downgrading my nvidia driver. Just make sure that you install the nvidia driver from terminal and not from GUI.

ubuntu22.04LTS desktop MBoard:z490 wifi:ax200 log:Bluetooth: hci0: Received unexpected HCI Event 0x00

It is a not good idea solution:
1,sudo service bluetooth restart
[may be you should sudo bluetoothctl disconnect [bluetoothId]]
2,sudo bluetoothctl power off
3,sudo bluetoothctl power on
4,sudo bluetoothctl connect [bluetoothId]

maybe protocal 5+ bluetooth not stable

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
