I have recently upgraded from 16.04 LTS and miss the option to suspend when pressing the power icon in the top bar, as no such option is available in 18.04.
One recent site suggests holding the power button down till a suspend option appears – it doesn't – it just powers off. I have set the settings option to suspend on pressing power button and indeed it does if pressed briefly but a long press turns the machine off.
Typing 'suspend' in the new Show Applications does bring up a button which does work but this is a round-the-houses way of doing things. It looks like shutting the lid on my laptop does suspend the machine. I leave my laptop with the lid down after I've turned it off, so I would like a quick way of doing it with the lid open and without hitting the power button.
Model is an Asus X555L
