--- Comment #2 from Chema <rondo...@gmail.com> --- Created attachment 156840 --> https://bugs.kde.org/attachment.cgi?id=156840&action=edit Powerdevil error log 2 I have done more tests and I have a news about this: it is not necessary to wait 15 minutes, as soon as KDE loses the HDMI signal, either by disconnecting the HDMI cable or by activating another computer on the KVM swtich, the error occurs from Powerdevil and power management stops working. I attach another log with this case, the crash starts at line 900: 28/2/23 23:07 systemd-coredump Process 3736 (org_kde_powerde) of user 1000 dumped core.
