Dear all,
Before I installed Gnome Desktop, nvidia-smi can show following information.
[root@vm10-0-6-21 ~]# nvidia-smi
Sun Nov 12 17:48:02 2017
+-----------------------------------------------------------------------------+

But after install gnome desktop with "yum groups install “GNOME Desktop” and run nvidia-smi again, I get following error information.
[root@vm10-0-6-21 ~]# nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
My environment is CentOS 7.3 64bit.
How to solve this problem?
Thanks a lot.
Michael
