Yes, I did reboot, way too many times…
My machine is not connected to an active directory most of the time, and was never connected when I experience this problem. Please note that I have never been able to connect to the laptop using NoMachine.
My own browsing of the logs seems to map the issue to a NoMachine inability to find my ID on the laptop. My profile is on a disk different than C (F in my laptop) could that be the issue?
