NoMachine stops accepting mouse and keyboard input

[webdawg]

So every once in a while for the past many years I connect to no machine.  This is Xorg – physical desktop control.

It would stop accepting inputs:  mouse – keyboard

I would restart w/ systemctl and nothing.  I recently did a few hour diagnosis session, and this fixes it:

PID=$(ps -o pid= -C nxnode.bin | tail -n1 | tr -d ' ')
echo "Tracing nxnode PID: $PID"
sudo timeout 6s strace -tt -e trace=openat -p "$PID" -o /tmp/nxnode.open || true
grep -F '/dev/uinput' /tmp/nxnode.open || echo "no /dev/uinput open() attempts recorded"

After attaching to the process, and letting it go – keyboard and mouse input springs to life.

Not sure of actual cause here – just know I have been dealing with this in Xorg for years.
