Thank you, but I've managed to install "nvidia" following: |
| 46 |
https://wiki.gentoo.org/wiki/NVIDIA/nvidia-drivers |
| 47 |
|
| 48 |
What confused me is the output from two kernels: |
| 49 |
|
| 50 |
linux-5.4.80-gentoo-r1 |
| 51 |
was installed with: genkernel --menuconfig all |
| 52 |
and "nouveau" was working OK on that kernel: |
| 53 |
|
| 54 |
grep CONFIG_EXTRA_FIRMWARE ../linux-5.4.80-gentoo-r1/.config showing: |
| 55 |
CONFIG_EXTRA_FIRMWARE="" |
| 56 |
|
| 57 |
The one below was compiled manually: |
| 58 |
grep CONFIG_EXTRA_FIRMWARE ../linux-5.4.72-gentoo/.config |
| 59 |
CONFIG_EXTRA_FIRMWARE="" |
| 60 |
|
| 61 |
Both had same output, so why one kernel was working the other didn't? |
