Ubuntu 17.04 nvidia-settings，如何从 sshd 运行？

我有一个简单的脚本，带有 GPU 设置：

#!/bin/bash
#nvidia-settings -a '[gpu:0]/GPUGraphicsMemoryOffset[3]=850'
nvidia-settings -a '[gpu:0]/GPUMemoryTransferRateOffset[3]=1900'
nvidia-settings -a '[gpu:0]/GPUFanControlState=1'
nvidia-settings -a '[fan:0]/GPUTargetFanSpeed=80'

但我无法ssh通过 crontab 运行此脚本。这些设置仅在实际屏幕/显示器上有效。

当我远程运行它时，出现以下错误：

$ ./gpu0.sh
Unable to init server: Could not connect: Connection refused
ERROR: The control display is undefined; please run `nvidia-settings --help` for usage information.
Unable to init server: Could not connect: Connection refused
ERROR: The control display is undefined; please run `nvidia-settings --help` for usage information.
Unable to init server: Could not connect: Connection refused
ERROR: The control display is undefined; please run `nvidia-settings --help` for usage information.

我该如何解决这个问题？
