Thank you, but I've managed to install "nvidia" following: https://wiki.gentoo.org/wiki/NVIDIA/nvidia-drivers What confused me is the output from two kernels: linux-5.4.80-gentoo-r1 was installed with: genkernel --menuconfig all and "nouveau" was working OK on that kernel: grep CONFIG_EXTRA_FIRMWARE ../linux-5.4.80-gentoo-r1/.config showing: CONFIG_EXTRA_FIRMWARE="" The one below was compiled manually: grep CONFIG_EXTRA_FIRMWARE ../linux-5.4.72-gentoo/.config CONFIG_EXTRA_FIRMWARE="" Both had same output, so why one kernel was working the other didn't?
