Bluetooth mouse stopped working after upgrading bluez to 5.80

General system Kernel, boot, graphics & hardware

Morning fellow EOSers,
After updating bluez from 5.79 to 5.80 my logitech mouse stopped working. I tried several times to repair it using the KDE gui and everytime it would fail. If I tried to pair it from the command line it would pair and connect, but restarting the bluetooth service would cause it to fail and it wouldn’t connect again until I repaired it.
Long story short I ended up downgrading bluez back to 5.79, and added bluez to the ignorepkg list. Hopefully this will get sorted out upstream.

Now that bluez is in the ignore list is there an easy way to see when a new version is available? or am i stuck checking manually?

You will get a warning when you run sudo pacman -Syu

: Synchronizing package databases…
gnome-unstable is up to date
core-testing is up to date
extra-testing is up to date
:: Starting full system upgrade…
warning: fakeroot: ignoring package upgrade (1.37-1 => 1.37.1-1)
there is nothing to do

Just made this example as demonstration.

hey I have this problem too after a recent update (yesterday) the only way I can get my logitech mouse to reconnect is by running the following commands after each reboot:

sudo systemctl stop bluetooth
sudo rm -rf /var/lib/bluetooth/*
sudo systemctl start bluetooth

then running:

bluetoothctl
agent on
default-agent
power on
scan on
pair XX:XX:XX:XX:XX:XX
connect XX:XX:XX:XX:XX:XX
trust XX:XX:XX:XX:XX:XX

But as of now I have to run this after every reboot. Things like my little bluetooth speaker were unaffected and still connect fine. If anyone can shed some light or help trouble shoot that would be appreciated.

had the same issue with my logitech mouse (Logi M196) and found an issue on bluez github:

That’s exactly what I had to do, downgrading solves the issue, bu hopefully it will be corrected upstream.

ugg I really should have known this. Thanks

I guess you would need to ignore the warning until it is passed the troublesome version. You know the rest of the story…

It’s not all Logitech mice, my M650 is working fine on Bluez 5.80 thankfully.

In my case using “sudo downgrade bluez” and "“sudo downgrade bluez-utils” to 5.79 version helped.

I have rebooted the system and luckily the mouse got connected. My mouse model is MX Master 3S.

hopefully this will be fixed with 5.82 update which should be coming out soon

Just updated bluez to 5.82 - my mouse (Logi M196) works fine again. :partying_face:
