Just an update on behaviour.

This morning when I woke up I opened my Samsung laptop lid and as expected the screen was blank. I had set up an alias in my bash with 'xrandr -- auto' to try so I pressed Super+t to get a terminal even though I was expecting to do this with no screen.

Much to my surprise, after a few seconds the screen came on. Unfortunately, the system was almost in a frozen state. Moving the mouse was very slow and jerky. It was so unresponsive I still had to do a forced shut down with the power button i.e. impossible to restart through the panel menu or even command line.

I should note that this "frozen" state where the machine is unusable has also happened randomly on a few occasions when the lid was not closed.
