SUMMARY The KDE Plasma freezes when using the conflicting blueman and bluedevil programs at the same time. The freezes occurs soon after the bluetooth service is started via systemctl. Dolphin was started too. I had to switch to the tty and reboot. STEPS TO REPRODUCE 1. Install both blueman & bluedevil 2. Start the bluetooth service using 'systemctl start bluetooth' 3. Try to pair a device and open Dolphin in the same time. OBSERVED RESULT A freeze can be observed. The display shows a static image. EXPECTED RESULT Normal work. SOFTWARE/OS VERSIONS Linux: 5.10.75-1-lts 64-bit KDE Plasma Version: 5.23.2 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION
Yes, you can only have one, since they both try to do the same thing and conflict with each other. You'll need to uninstall blueman or unload its systemd service.
Hi Nate, the problem described by my obviously is a bug. Because Plasma crashed and the behavior and the result was awful. Plasma needs to be modified some way in order to prevent using more than one bluetooth manager at the same time. It needs a detection mechanism. The task bar was showing both widgets. This is an unacceptable absurd in 2021 and this makes me want to join projects such as KDE. Of course i left only bluedevil. You can't deny that this is a problem. ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Monday, November 8th, 2021 at 8:59 PM, Nate Graham <bugzilla_noreply@kde.org> wrote: > https://bugs.kde.org/show_bug.cgi?id=444914 > > Nate Graham nate@kde.org changed: > > What |Removed |Added > ---------------------- > > CC| |nate@kde.org > Status|REPORTED |RESOLVED > Resolution|--- |NOT A BUG > > > --- Comment #1 from Nate Graham nate@kde.org --- > > Yes, you can only have one, since they both try to do the same thing and > > conflict with each other.

Well, the problem was caused by user error--mistakenly installing two components that are trying to handle the same thing. We could add something to protect the user from their own decisions, but that becomes a can of worms really quickly, as it's quite difficult to explain this kind of situation to a normal user. Arguably if there's a desire to prevent this condition from happening, it should be handled in the distro's packaging, by marking blueman and bluedevil as mutually exclusive, so that it's not possible to have both installed at the same time; it's never a valid combination. Can you explain why you installed blueman in addition to bluedevil?
Hi, i just decided to try blueman but indeed it was not marked as a conflicting package and Arch didn't warn me. Of course i went with the Plasma native bluedevil after that. So i have create a ticket in the Arch community to deal with this. Thanks.
