--- Comment #7 from Jakob Petsovits <jpe...@petsovits.com> --- Thanks. These are only regular logs, not verbose - did I make a mistake in the README instructions for setting the QT_LOGGING_RULES environment variable? Please double-check that this was set and powerdevil was restarted. The main thing we can learn from these logs is this line: > org.kde.powerdevil: [DDCutilDisplay]: ddca_set_non_table_vcp_value -3023 Which basically tells us that setting the brightness via DDC/CI failed. According to the libddcutil source code, this result is DDCRC_VERIFY, described as "read after VCP write failed or wrong value". I.e. the monitor was present to communicate with the system and accepted the command, but ignored it so the brightness was still unchanged. I think the theory is still the same. I'd still be interested in more detailed powerdevil logs. -- You are receiving this mail because: You are watching all bug changes.
