I can't set the brightness under hybrid mode graphics mode in Fedora 31 and discrete graphics don't work at all.
I have UEFI firmware version 1.27, I am running Fedora 31 with linux kernel version 5.3.12-300.fc31.x86_64.
I compiled and installed the NVIDIA driver version 418.88 from their website and installed it per the instructions on this blog/site
I have also tried to install Ubuntu 19.10 with the same problem...no brightness controls.
Is there any kind of an ETA on a fix for this issue? I have seen other posts and just wanted chime in and say that I can't find a work around at all on linux. My retinas hurt as I type this and I really can't use the display with full brightness.
I have tried some work arounds like manually switching to the intel display profile and dimming the display using xrandr....and don't get very far as this seems to break when I turn on the night light mode. It seems to ignore the xrandr settings when the laptop enters night mode.

I'm working on getting a P1 Gen 2 with OLED display working in Kubuntu.
