--- Comment #44 from Stefan Walter <k...@stefanw.anonaddy.com> --- @andy: The error originates in libddcutil, which is used by powerdevil to control the brightness of external monitors. Are you using this feature? If not, you could also edit the service to start it with POWERDEVIL_NO_DDCUTIL=1, as described here: https://invent.kde.org/plasma/powerdevil/-/blob/master/README.md?ref_type=heads#troubleshooting-ddcci-monitor-brightness-controls -- You are receiving this mail because: You are watching all bug changes.
