Bug ID: 448623 Summary: Only laptop screen is dimmed, external monitors are not affected Product: Powerdevil Version: 5.23.5 Platform: Kubuntu Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: plasma-b...@kde.org Reporter: tomash...@gmail.com Target Milestone: --- SUMMARY If System Settings> Power Management > Dim screen is checked and a time is set, after the specified time, only the laptop screen dims, not external monitors. "Screen Energy Saving" has effect on all the monitors. My monitors certainly support different brightness. They are connected through USB-C and DP. They are recent Dells. It does not have to do anything with Primary monitor - I tried to set it to external monitors but it had no affect. I am on X, Kubuntu 21.10. -- You are receiving this mail because: You are watching all bug changes.
