我有这样的 quemu-kvm 配置 - 主机 (linux) 上的 IGP 和客户机 (windows) 上的 Nvidia。我在 linux (arch dist.) 下将 nvidia 驱动程序列入黑名单。
在我运行 Windows（Windows 风扇安静地工作）之前，有没有办法在 Linux 下设置 GPU 风扇速度（它非常吵）。
提前致谢！

是的，在 Linux 下设置 nvidia 显卡的 GPU 风扇速度是可能的，请参阅此askubuntu.com 上的相关问题。 简而言之：
- 编辑您的
xorg.conf并添加Option "Coolbits" "4"到Section "Screen"。或者直接执行nvidia-xconfig --cool-bits=4，这将为您生成一个全新的xorg.conf并为您设置此选项。这将启用风扇控制设置。 - 重新启动 X 或计算机运行后
nvidia-settings。您将在下方找到一个新的 GPU 风扇设置热设置。您也可以通过命令行来控制它，首先通过启用此设置nvidia-settings -a "[gpu:0]/GPUFanControlState=1"，然后通过强制执行特定的风扇速度nvidia-settings -a "[fan:0]/GPUTargetFanSpeed=65"（在本例中为 65%）。
