Same issue on Arch Linux with 6.0.3 and Wayland. For me, it turns down the brightness to 5%. This issue only started to occur when I upgraded from 5.27 to 6.03. I think 5% was the brightness I had my monitor set to when I performed the upgrade. So my guess is that since version 6 this value isn't overwritten correctly anymore. Did something change with how the monitor brightness is being saved between 5 and 6?

I'd say it's probably "Dim automatically", which also reduces monitor brightness. Could you try out disabling that instead of all DDC brightness controls? If that's the culprit, that would make this bug report a duplicate of Bug 452492 (*). (*) The short version is that Plasma/PowerDevil doesn't (yet) store and restore brightness by itself across sleep or disconnection. A lot of work has gone into per-display brightness support, which brings us closer to getting this fixed properly. But we're not quite there yet.

A little bit, but not in a way that would persist your original brightness value at the time of upgrade. As mentioned above, Plasma doesn't store monitor brightness in the first place and that's the root of some bugs because the monitor isn't always around when Plasma wants to make a change to brightness or revert it to the previous value. 🐛🧹 ⚠️ This bug has been in NEEDSINFO status with no change for at least 15 days.

Thank you for helping us make KDE software even better for everyone! 🐛🧹 This bug has been in NEEDSINFO status with no change for at least 30 days. Closing as RESOLVED WORKSFORME. Happened to me right now. I have brightness set to 20%. Set my power config yesterday to "Dim automatically" after 4min, "Turn off screen" after 6min, sleep after 9 minutes and use hybrid sleep. Today I noticed new Manjaro update, so I leave my PC when it was updating. When I return and wake up my PC, the brightness was set to 6%.

Note that I'm looking at this issue - not sure if there's a separate issue from Bug 452492 or if this is an outright duplicate, but the problem is known and a solution is on my list of things I want to fix in the next little bit.
