Public bug reported:
There seem to be quite a few instances of this bug occurring with other
users but no real solution appears to have been found. This occurs most
commonly when doing processing on the GPU with CUDA applications such as
TensorFlow and MATLAB. Killing lightdm over SSH usually fails and a hard
reboot is required, initiating reboot command over SSH results in an
unresponsive machine.
I've also had it occur while logging into VNC over SSH in which case the
machine becomes completely unresponsive and no logs are written to
indicate what has occurred.
