--- Comment #15 from zvova7...@gmail.com --- rjawiygv...@gmail.com, Could you please put this into /etc/environment and catch the situation when you have unavailable brightness controls? QT_LOGGING_RULES="*powerdevil*.debug=true" Then save the logs: journalctl -b -t org_kde_powerdevil > /tmp/powerdevil.log ... and attach here. Just wan't to understand what is going on. -- You are receiving this mail because: You are watching all bug changes.
