nvidia gpu fan speed control

nvidia在linux上控制风扇速度,需要起X,在无显示器链接的服务器上显得有点坑,这里汇总一下整个流程

1.nvidia-xconfig --cool-bits=4 生成xorg.conf

2.在X已启动的前提下,用nvidia-settings -q all | grep -i fan 列出关于风扇的所有属性,其中应该有 GPUFanControlState,把它设置为 1,然后再根据需要设置 GPUFanTarget,例如nvidia-settings -a [gpu:0]/GPUFanControlState=1 -a [fan:0]/GPUTargetFanSpeed=70

3.如果X没有启动,管理员权限执行 X :1 & 启动X,注意,这里:1需要根据实际情况修改,例如改为2、3。

主要改动是针对不同GPU,修改xorg.conf Device BusID,添加CustomEDID,欺骗X链接显示器,启动不同的X,并指定环境变量DISPLAY(例如=:2、=:3),之后再执行nvidia-settings。这里提供一个xorg.conf模板
