Update: unfortunately I couldn’t fix the either standby/hibernate function (which I feel is important in a very portable laptop with a small battery), so am reverting to Manjaro.

Tried the latest stable Debian, but it didn’t have drivers for the network card, so would have been difficult to update, so I didn’t install it.

Further to the above, some linux work on the hinge sensor to detect tablet mode exists.
