I can confirm that this bug affects me too, but unfortunately the workaround suggested by @sureshot16 that worked for some users here did not work for me, so I think it wouldn't for some makes and models.
For reference, I'm on a laptop with the following specifications: Lenovo Legion Y540 NVIDIA GTX 1650 Mobile/Max-Q Ubuntu 20.04 kernel 5.8.0-38 generic I've had brightness issues on previous versions of the NVIDIA drivers as well, somewhat constantly, but they'd stop once I suspended the laptop and opened it up again once. This is not the case for the 460 driver. -- 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
