[Kernel-packages] [Bug 1905591] Re: no brightness control after update from 450 to 455
@ddadap: No, nvidia-460 does not fix this regression. I've just tested
nvidia-driver-460 (460.32.03-0ubuntu0.18.04.1) and I observe that it
still misbehaves exactly as described above for 455: The initial
brightness is unusually dim and cannot be changed by any means. (Also,
just like 455, some pixel garbage appears during mode switch).
Reverting to 450 restores normal brightness functionality.
This regression makes nvidia-460 (and nvidia-455) unusable, and
manifests on multiple modern laptops.
@djve60: FYI, the (still defective) nvidia-460 packages are now available in
the archive, making testing 460 pretty painless at least:
To install 460:
sudo apt install nvidia-kernel-common-460 nvidia-driver-460
To revert to 450:
sudo apt install nvidia-kernel-common-450 nvidia-driver-450
@djve60, I recommend that you go ahead and test 460 that way to
determine whether your P76 sees any benefit or still fails like my X1
Extreme.

no brightness control in {455,460} after update from 450
Status in OEM Priority Project:
New

Triaged
Bug description:
On my Lenovo X1 Extreme with GPU: NVIDIA Corporation GP107M [GeForce
GTX 1050 Ti Mobile]
Updating to nvidia-driver-455 results in loss of brightness control.
On boot, the laptop display brightness is somewhat less than fully
bright and cannot be changed. The brightness up/down keys do pop up
the gnome gui brightness widget, and /sys/class/backlight/nvidia_0/*
values do change, but the actual display's brightness does not.
Problem occurs with either version of nvidia-driver-455 (the archive
or the ~graphics-drivers/PPA). Normal functionality returns if I
downgrade to any version of nvidia-driver-450.
Note also that manually applying this to
/lib/systemd/system/nvidia-persistenced.service has no effect on the problem:

Not me. I'm using Ubuntu 20.04. Until it's made available by the software update mechanisms I won't touch it. But "brightness regressions"? We're talking about basic control. How does passing regression tests helps this issue? Or did people ignore regression tests before releasing the 450 series?
