I had already tried the "EnableBrightnessControl=1" kernel parameter a year ago but I tried it anyway, no effect. However, trying the suggestion of @paulplusx I can happily report that brightness works flawlessly after using "nvidia.NVreg_RegistryDwords=EnableBrightnessControl=1" with the latest 495 driver. nvidia-smi shows GPU is loaded and opengl works on glxgears and CG:GO. If someone can test CUDA that would be great.
Thank you everyone and especially @paulplusx for solving this issue, hopefully this means we can close this bug soon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1905591 Title: no brightness control in {455,460} after update from 450 To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1905591/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
