--- Comment #5 from Jakob Petsovits <jpe...@petsovits.com> --- (In reply to Wren Turkal from comment #4) > I think you are saying that Plasma doesn't remember brightness ever for a > plugged in monitor. Is that correct? Sorry, I phrased this poorly. Plasma will of course remember brightness for an external monitor. What it will not do (for the time being) is realize when the monitor itself has initiated the brightness change through its own hardware buttons. We can read the monitor's brightness values but we won't get notified when a change happens, so for now we left "read brightness again" heuristics for a later time. As of Plasma 6.3, we only read brightness when the monitor is first detected to initialize settings for a monitor that KWin has not seen before. > Just to give you a little more about my use case.

What I'm reading is that you're indeed using Plasma's brightness slider to re-adjust the brightness, you're not using your monitor's hardware buttons to do this. By using Plasma's brightness slider, the brightness would get stored and should indeed be restored next time your monitor gets connected again. The fact that this does not happen (reliably, at least) is indeed a bug. If you can collect some logs as described earlier, we may find an indication of what's going wrong. -- You are receiving this mail because: You are watching all bug changes.
