If it's on one of the built-in Intel graphics outputs, then it will likely work out of the box (though of course none of the desktops will understand where it's supposed to be and probably put it in the wrong place, etc...).
If it's some crazy piece of hardware Asus found, then maybe never.
Changing display layout on modern Linux desktops is really really simple IMO.
You just open display settings and drag them into the layout you want.
xrandr --output $touchpadscreen --below $builtinscreen
And, even if the hardware can be hacked for Linux the question becomes, how can it be made functional in a desktop environment independent way?
Been doing R&D for a similar concept for several years, a detached video enabled trackpad. The key functionality which all concepts to date lack, is being OS agnostic and allowing end-user customization of functionality.
It's a good effort, but is likely only the beginning...
Do you mean that I can have a laptop with an integrated secondary display to have a Zabbix monitoring panel on it?
This might be the sysadmins' favorite laptop!
What a time to be alive!
I have a retired smartphone on my desk showing a live feed to my doorbell cam, and I could see myself using that Zenbook's touchpad screen as a Zoneminder window.
What makes this totally different from the touch bar is with the touch bar, you have to wait for developers to add support in their products (or as a dev, write your own tooling). Apple has the muscle to simply make everyone support their crappy bar.
The ZenBook screen is usable right away by anybody. You can just drag any window there. It can be your Steam chat while playing a game, it can be a browser with a Twitch stream or soccer game running in the background while your program, it can be your color pallet for Resolve while editing video ...
It can be used for a lot of things the end user can take advantage of immediately without waiting for a developer to make explicit use of it.
I wonder if it will work on Linux.
