Summary: Powerdevil bug killing my bluetooth?
Product: Powerdevil
Version: 5.20.5
Platform: Other
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: k...@equaeghe.nospammail.net
Target Milestone: ---
SUMMARY
I have the problem that sometimes my bluetooth is killed. Namely, my mouse and
headset stop working and I need to stop and start the bluetoothd service to get
them back. (Sometimes, it is only the mouse and it recovers after a few seconds
by itself.)
In the logs, the activity around this is always preceded by
org_kde_powerdevil[…]: QObject::disconnect: Unexpected nullptr parameter
org_kde_powerdevil[…]: QObject::disconnect: Unexpected nullptr parameter
(However, this appears more often than that bluetooth falls away.)
It is followed by
acpid[500]: input device has been disconnected, fd 23
dbus-daemon[504]: [system] Rejected send message, 0 matched rules;
type="method_return", sender=":1.77" (uid=1000 pid=1711
comm="/usr/bin/pulseaudio --start --log-target=syslog ") interface="(unset)"
member="(unset)" error name="(unset)" requested_reply="0" destination=":1.174"
(uid=0 pid=40907 comm="/usr/libexec/bluetooth/bluetoothd ")
My takeaway is that there is some bug in Powerdevil (related to ‘Unexpected
nullptr parameter’). It may be that this bug triggers my bluetooth issues. I'd
like to investigate that idea
STEPS TO REPRODUCE
Unknown, but happens every few hours.
