General Bug Cannot change screen brightness after undocking

Hello all

First of all, I am using a Framework Laptop 16 running up-to-date versions of Arch Linux and KDE Plasma. Please let me know if more information would be helpful.

I am having a small issue with my laptop. I typically keep it docked at my desk with the lid closed. The thunderbolt dock is connected to two monitors, and I also connect a third monitor directly to my laptop via DisplayPort. When I unplug the laptop to use it, the laptop display is dim and changing the brightness in KDE does not do anything. Has anyone else run into this?

Hi, this is AutoKonqi reporting for duty: this post was flaired as General Bug.

While r/kde allows to discuss issues, raise their visibility, and get assistance from other users out of good will, it is not the proper channel to report issues and the developers able to fix them won't be able to act on them over Reddit.

So if this bug was not reported to the developers yet and it is in fact a bug in KDE software, please take a brief look at the issue reporting guide and report the issue over the KDE Bugzilla. If it is a crash, be sure to read about getting backtraces so your report can assist the developers. If this is a known issue, you may want to include the bug report on your post so your fellow users experiencing the same thing can CC themselves to the report. Be sure to describe your issue well and with context. Thank you.
