Bluetooth not working in Ubuntu 20.04 LTS #208

abhishekshree commented 3 years ago

I tried every possible way to make the bluetooth driver work but it seem to fail all the time. I need to attend zoom session a lot these days so this is really becoming a major concern for me these days.

Some results from my terminal: ~ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 04f3:0c00 Elan Microelectronics Corp.

It'd be really appreciated if anyone helps me out here.

I dont know why but there is problem using both card. I use Fedora rhel debian and ubuntu with different computers and they have rtl8821ce. Only Ubuntu ı cannot use bluetooth when I modprobed 8821ce module.

You're saying nothing can be done about it @Zaryob ?

Zaryob commented 3 years ago

probably about ubuntu kernel. Try another kernel module for ubuntu (mainline or lts kernel provided by ppa repository of kernel group.)

Did you make it work @abhishekshree ? I have the same issue. Kernel Version 5.5.17-1. Debian based System.

abhishekshree commented 3 years ago

No @CITIZENDOT It is a really weird bug.

Hi, how do this ?

abhishekshree commented 3 years ago

Closing this issue as apparently it can't be fixed just yet.

kascesar commented 3 years ago
