Error is 5: Input/output error

[Only1KW]

I just installed NoMachine on my fresh Linux installation as the server.  When I try and connect for the first time from the client, the client posts the error “Could not start the display server.  Error is 5: Input/output error”.

I see the following relevant output in the logs on the server below.

nxd.log
