 |
|
| Hi, I'm following the guide for switching between nvidia and nouveau, so I copied my kernel sources to a new directory, built a new kernel, installed the modules with make modules_install, but now emerge @module-rebuild doesn't install the modules in nvidia kernel directory. No error during the compilation. |

Why you copied kernel sources?
Anyway nvidia-drivers is installed? emerge @module-rebuild work only if nvidia-drivers is already installed.

| Nvidia-drivers is already installed. I copied kernel sources to have a nvidia kernel directory, and I selected it with eselect, but modules are not in /lib/4.14.32-gentoo-nvidia |

| I need to have 2 different directory for nvidia and nouveau beacause it searches for modules in the nvidia directory (/lib/modules/4.14.32-nvidia, as I renamed my kernel like that) |

If you use 'Switching using two kernels On Boot' you should only have 2 kernels compiled in /boot, one normal and one with suffix -nvidia (but is same compiled kernel), then is /etc/local.d/nvidia.start script that load correct module (nvidia or nouveau) dependency of kernel name

| I need to have another directory for nvidia kernel and modules because otherwise I can't load modules beacause it searches for modules inside"/usr/lib/nameofmykernel-nvidia" and can't find them |

| There is never a need to copy the kernel sources. At worst, you might need to build two copies of the kernel with differing .config files. According to fedeliallalinea's post, you don't even need that. If that is not your experience, then either the instructions are wrong or you deviated from them in some way. We would need to see exactly how you configured each kernel to understand which is the case. |
