Description Jarl Gjessing 2025-06-14 13:32:56 UTC

I ran apt upgrade some time ago and after that, my bluetooth mouse and keyboard does no longer connect automatically when logging into KDE.

It is solved pretty simple by turning off bluetooth and then turning it on again..

Some of the latest packages I consider being relevant was:
linux-firmware or OVMF maybe?

STEPS TO REPRODUCE
1. Upgrade to the latest packages in KDE neon
2. Reboot
3. Login using laptops keyboard

External bluetooth keyboard and mouse no longer works


Expected that devices worked as before upding.

Now it seems as the behaviour has changes, because not only does it not connect at boot. But now, is suddenly disconnects the devices and sometimes the bluetooth turns of and then on, thereby disconnecting, and not connecting the devices again.

This issue is not seen in windows, so it does not to me, look like a hardware issue

And now it happened for the 3.rd time since I updated the ticket last. So it is almost each 5 minutes, rendering my computer unusable since my input devices are bluetooth only :-(

I just reinstalled from scratch and this fixed the issue.
So, I'm not sure what to do with the issue now.

Comment 4 Bernie Innocenti 2025-12-10 10:04:06 UTC

I can't repro with Plasma 6.5.4 + Frameworks 6.21 + QT 6.10.1 + bluez 5.85 + Linux 6.18 . In fact, I have the opposite problem: there's no UI to disable autoconnect for a device once it's paired ;-)

Since the original reporter is also unable to reproduce, I propose closing as WORKSFORME. Please reopen if
