[Bug 2148630] Re: Brightness control does not work at all on ROG Zephyrus G14 GA403WP laptop

Thanks for confirming that brightness dimming works again on kernel 7.0.0-15-generic — that's great news. I'll go ahead and mark this bug as Fix Released. One quick note: you mentioned concern about Ubuntu potentially missing the pixel-shifting anti-burning feature that Asus provides on Windows. That's a separate (and valid) concern from the brightness-control fix we just confirmed. If you'd like, feel free to file a new bug specifically about OLED pixel shifting support — that would be best tracked as its own issue rather than folded into this resolved report. Thanks again for your help testing and closing this out. ** Changed in: linux (Ubuntu) Status: Incomplete => Fix Released ** No longer affects: linux (Ubuntu Resolute) ** Changed in: linux (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are subscribed to linux in Ubuntu.

The brightness control for the built in display on this laptop does not work at all, booted into the Resolute daily live distro. Ubuntu 26.04 "Resolute Raccoon" - Daily amd64 (20260415) Happy to pull logs once I can work out which package is actually responsible for display control. This is an OLED so it's pretty critical for dimming to work.
