I am currently setting up such a device, Asus ZenBook Flip 15, UX561UD from 
2018, and the new Dell XPS 15 9575 2-in-1 will follow in a week or two.

For the Asus, the generic laptop functions work out of the box with just
two small niggles (bugs are filed) and very little is missing to make
conversion features work out of the box. Rotation sensors and touch
works perfectly fine (this is on Wayland, X has fewer working touch
gestures but basics work too). What is missing is just:

1. Automatically deactivate touchpad when folding to tablet. (The
keyboard already turns off. The keyboard has a working key to deactivate
the touchpad, these two things only have to be wired together)

2. The new on-screen keyboard (from Gnome 2.28) activates automatically
(even when deactivated in Accessibility settings) when touching the
search box in the Gnome Activities menu and the applications overview
menu. I found no other place where it triggers, not even the first-class
Gnome applications like Web. It just has to trigger for every text entry
box and we are good.

3. Important and not yet mentioned: This device type has a tent mode,
typically for video watching. (It's great because most laptops have air
intake grills and speakers at the bottom, which sucks e.g. in bed. Tent
mode solves this nicely). However, in tent mode the stereo speakers swap
positions relative to the screen, so the stereo channels have to be
swapped. This is quite simple on the fly without touching a config file
by:

pactl load-module module-remap-sink sink_name=reverse-stereo master=0
channels=2 master_channel_map=front-right,front-left channel_map=front-
left,front-right

Then switch to it by:
pactl set-default-sink reverse-stereo

One can also switch in the sound control panel. It will disappear after
pulseaudio restart

I didn't come up with the pulseaudio stuff or try it out yet. Credit
