Brokent 515.76 on new kernel

[eimantas.es]

Just want to report that Nvidia driver 515.76 does not work with kernel 6.0. When I boot Ubuntu with 6.0 kernel, Nvidia driver just doesn’t work. Latest kernel I can use is 5.19.12

It works fine here.

that’s what it says for me:

I assume you are on Ubuntu Jammy. The steps that are working for me are:

1. Install gcc-12
2. Remove and symlink /etc/alternatives/cc to /usr/bin/gcc-12 (nvidia dkms is using cc)
3. Change the following lines in /usr/src/nvidia-515.65.01/nvidia-drm/nvidia-drm-helper.c

4. Reinstall the kernel headers to run dkms again (apt purge linux-headers-xxx-generic, dpkg -i linux-headers-xxx-generic.deb).

Oh, I had no idea I have to use newer gcc, and link it, after doing those steps you provided, it all works now! Thank you!

There was an error in the log about trivial-auto-var-init which gave me a hint.
