[Bug 1947432] Re: [HP OMEN 846A] Display backlight and brightness controls are not working
It seems that installing the 495 drivers from the Nvidia website has fixed this issue for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947432 Title: [HP OMEN 846A] Display backlight and brightness controls are not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-470/+bug/1947432/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1947432] Re: Display backlight and brightness controls are not working
** Description changed: The screen brightness is stuck at 50% of the max output and the brightness controls/slider do nothing at all. This issue started happening with the nvidia-driver-470 package even - before I upgraded from 21.04, and it doesn't happen with 465. The bug + before I upgraded from 21.04, and it doesn't happen with 460. The bug manifests in both X11 and Wayland. (and GDM itself before logging in) Setting nvidia-drm.modeset to 1 doesn't seem to affect it either.
