将 Coolbits 设置为 20.04 而不吹 X

Question

我正在尝试将 Coolbits 设置为 20.04，以获得手动 GPU 风扇控制。

10-nvidia.conf我编辑了已经存在的nvidia X 配置文件/usr/share/X11：

Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    Option "Coolbits" "28"
    ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg"
EndSection

请注意，我刚刚添加了Option "Coolbits" "28"

这没有任何效果。

根据我的配置，在 20.04 中设置 Coolbits 的正确方法是什么？

Answer 1

根据我的理解，coolbits 选项应该位于“Device”部分而不是“OutputClass”部分。

对于仅手动 GPU 风扇控制，您可以将 Coolbits 设置为 4。28 也可以，因为它是 16+8+4（每个二进制位都是不同的位），还为您提供了另外两组选项（我认为一组是过压） (16)，另一个是更改每个时钟的性能设置 (8)。

Answer 2

你走在正确的轨道上。它是Option "Coolbits" "13"。另外，我的conf 文件xorg.conf位于/ect/x11（您可以使用 生成一个nvidia-xconfig）。它看起来像这样：

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 455.28

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 440.82

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 435.21
