@Mumuskeh Most of the time there are no breaking changes between e.g. 6.14.0 and 6.14.11 so the patch works for all of them.

There is a separate patch for 6.15.x.

Here Ubuntu 24.04.1 kernel 6.14.
That patch works.
I see then installing kernel 6.14 and using driver 470 an extreme slowdown playing video and moving mouse pointer in few softwares. The GPU usage goes to 100 % in simple tasks.
I have used in kernel the setting nvidia-drm.modeset=1
Have an nice week and thanks very much for doing that good deed.

Thank you very much for this...

The patch works on Ubuntu 24.04.2 and kernel 6.14.0-27-generic.

My two nvidia cards (Quadro M4000 & Tesla K80) are recognized by the driver. However, it only identifies just one of the two Tesla k80's chipsets. It's not perfect but better than nothing.

BTW @Augusto7743, to avoid this:

You need to blacklist nouveau drivers.

@egoipse
Oh yeahh ... nouveau are blacklisted.
In moment that issue not are happening very much.

hello, I don't know if it would be too much trouble if you could help me how to install this patch for nobara 42, before I used pop os with a 6.12 kernel and I followed the steps left by the author and they worked for me, but I don't know what to do here haha

@ItzDarkGod See https://github.com/joanbm/nvidia-470xx-linux-mainline, to install it should be enough to download the repository and run the ./install script.
