DGX Station: The Symbolic Link to /usr/local/cuda Is Missing

DGX Station: The System Cannot be Resumed After Suspension

Issue (fixed with EL7-22.02)

The DGX Station cannot be resumed after being suspended either from the desktop GUI or by using the systemctl suspend command. Pressing a keyboard key or the power button when the system is suspended has no effect: The display remains dark, it is not possible to log in to the system, and the system does not respond to a ping command from a remote host.

Workaround

To avoid this issue, do not suspend the system.

If you encounter this issue, turn off the power to the system and then turn on the power to the system again.
