nvidia-xconfig --cool-bits=4 后鼠标出现问题 
nvidia-xconfig --enable-all-gpus
nvidia-xconfig --cool-bits=4

从forums.developer.nvidia.com在 Ubuntu 18 上使用我的双 Titan RTX。这使我可以使用 NVIDIA X 服务器设置手动设置风扇速度。否则，GPU 在训练期间会运行得非常热（86C）。当我将风扇设置为 100% 时，训练期间的温度为 66C。

升级到 ubuntu 20.04，除了设置后，一切都非常稳定coolbits=4。当我这样做时，我得到了手动风扇控制，但屏幕超时并变暗后，我登录，鼠标没有出现。使用重新启动<CTRL><ALT>T以获取终端（无鼠标），sudo reboot登录，一切都很好，直到屏幕超时后变暗。

删除 /etc/X11/xorg.config，重新启动，然后一切都恢复正常，即使屏幕超时并变暗，但没有 GPU 风扇速度控制。

非常具有重复性。

还有其他方法可以在 NVIDIA 上启用手动风扇速度控制吗？

我尝试了 sudo nvidia-smi --gpu-target-temp=70，但这对风扇速度没有影响。

这/etc/X11/xorg.config由...制作nvidia-xconfig
