That's a very intersting observation, Mark. Thanks! I'll keep an eye on that, i.e. check if I can jump to another TTY before I shutdown.
On my laptop (Lenovo X220) I have noticed that the indicator lights (LEDs) for wifi and power(!) turn off, while the screen stays on. Marks observation plus this one points in the direction of problems with the graphics driver. My graphics card is Intel. Should be a GMA 3000. lspci says:
