以下为本人在ubuntu18下的实践体验,并不一定严谨。
如果自己已经安装NVIDIA驱动,在命令行输入:nvidia-smi,却输出如下提示
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
1、原因是NVIDIA驱动无法与电脑“独显”连接,也就是说目前电脑在“集显”下工作,这个时候一般重启电脑即可。
2、如果1不成功,可能是显示屏接口接到电脑主机的“集显”插口上了。那么将显示屏接口接入“独显”插口上,然后关机并重新开机即可(更换插口后,显示屏无法显示,这个时候只能长按电源关机,然后重启。或者先关机,再更换插口,再开机)。
注:有人不清楚电脑主机上“集显”与“独显”接口的位置,参考下图(本人为dell工作站,其他台式自行查找)
