I'm using an Acer Switch 5 (a compact laptop with detachable keyboard) with Ubuntu 18.10 + latest updates. Generally the experience is great, but there is a frustrating niggle:
When I close the keyboard up against the screen (lid close) the laptop sleeps as expected. But when I open it again, the keyboard and it's built-in touchpad are dead (although the laptop otherwise wakes as expected). To make them work again, I must detach the keyboard and re-attach it. Very cumbersome.
Interesting side note: if I manually put the laptop to sleep, either by pressing the sleep/power button or by selecting suspend/sleep from the power menu and THEN close the lid, when I open the keyboard again, it wakes the laptop and everything works! Hmm.
This is the first time I have tried Linux on the device -- so it's not a regression (i.e. I have never known it to work in the past).
So: do you smart people here know if there is a different sleep action happening when I select suspend/sleep from the menu vs just close the lid? Or do you think there is some confusing hardware/firmware magic happening when the keyboard closes against the powered on laptop?
My current work around is to manually sleep the laptop myself each time before closing my lid. But that is not ... nice.
Thanks for any input!
