I installed the latest version of Manjaro on my Acer Aspire 5740G laptop. The OS is working great on it! I have just one little annoyance which seems to persist: Bluetooth. I need it for the BT mouse I use… this causes my mouse to not work on login or stop working after some minutes / hours.
Sometimes bluetooth doesn’t get enabled when I log in, or becomes disabled after a certain amount of time. When this happens the button to enable Bluetooth in the KDE System Settings - Hardware - Bluetooth menu is available but clicking it does nothing, I need to reboot and hope it works next time. The bluetooth button on the laptop has a blue light to indicate it’s on but pressing it has no effect.
Do you by any chance have an Intel AX200 or AX201?
Can you please edit this output and either put ``` before and after the output or highlight the output and click on </>?
It makes it a lot easier to read.
AX200 & AX201 are having issues currently due to regression from the linux-firmware package as of 2021. Someone posted about it a few days ago as well .
You need to temporarily use linux-firmware v20201218.646f159-1, this is a package version from 2020-12-18
I got my package from Arch Linux Archive
sudo pacman -U https://archive.archlinux…

How do I check, what do I check for? If you mean CPU that’s an Intel Core i5.

Please provide inxi -Fza

You check for if your network/bluetooth card is Intel AX200 or AX201

Nope, it is a different bluetooth device. Hopefully someone else can help you. Or you can look that up to see if anyone else had the same issue.
With some research I finally found a command to fix Bluetooth at runtime after it breaks, saving me from having to restart the laptop every 15 minutes:
sudo rfkill block bluetooth;sudo rfkill unblock bluetooth;sudo systemctl restart bluetooth.service
First two commands seem to be required, the third is added for completion’s sake. Using systemctl alone to restart the BT service won’t affect the issue, only rfkill seems to.
