nvidia drivers 455.38-1 and RTX 3070

I have issues managing to make my brand new Asus RTX 3070 Dual to work. I previously had a GTX970 that was working perfectly and the nvidia driver installed.
So today I just swapped the boards and nothing seem to work. I have the latest nvidia driver version which I believe is supposed to support my hardware so I'm not sure what is going on.

Also I had upgraded my kernel to 5.9 and I saw that the nvidia driver was incompatible so I downgraded

uname -a
Linux leo-arch 5.8.7-arch1-1 #1 SMP PREEMPT Sat, 05 Sep 2020 12:31:32 +0000 x86_64 GNU/Linux

lib32-nvidia-utils 455.38-1
nvidia 455.38-1
nvidia-settings 455.38-1
nvidia-utils 455.38-1
opencl-nvidia 455.38-1

Anyone managed to make it work? Any pointer would help.

This is expected to break, your nvidia module doesn't match the kernel.

From what I've been hearing 455.38 should've fixed the issues with 5.9 (... and the brokeness only concerns CUDA and OpenCL, normal desktop usage/gaming was unaffected)

If you want to stick to an older kernel regardless you need to install the linux-headers package of the same old kernel and the current nvidia-dkms package so the module build happens on your system.

Linux 5.9.2 + nvidia 455.38 appears to have fixed the CUDA/OpenCL issue. I haven't stress-tested, but Blender is back to allowing CUDA for GPU compute.

Do you have more info on that? With my GTX 1070 upgrading to kernel 5.9 caused rendering artifacts in Firefox and it caused KDE widget icons to stop displaying.

Temporarily switching to the LTS kernel totally solved the KDE widget icon problem, but as of today I still cannot run Firefox with hardware acceleration turned on while using linux 5.4.75-1-lts and nvidia-lts 1:455.38-3.

You should probably open another thread for this. Maybe including a xorg/journal log. What can happen here regardless of what's what (with every card and driver including OSS ones) is a race condition in loading the graphics subsystem fully before attempting to start xorg.

I did more troubleshooting and here is my conclusion:
prior to linux 5.9 and nvidia 455.38 I was able to use webrender and hw_acceleration in Firefox, even though nvidia was not officially supported by Mozilla. I had these user prefs set:

user_pref("gfx.canvas.azure.accelerated", true);
user_pref("gfx.webrender.enabled", true);
user_pref("gfx.webrender.all", true);

With linux 5.9 and nvidia 455.38, I had to change those all to false. I am able to reproduce this. It also affects linux-lts 5.4.75-1 / nvidia-lts 455.38-3.

Where would be the best place to report this?
