Between Linux 6.6.15 and Linux 6.9.0 the display output is broken. It looks like a hardware issue where only half of the panel is used and it presents glitches.
See
- https://gitlab.freedesktop.org/drm/intel/-/issues/10334
- https://github.com/torvalds/linux/commit/18846627ef1210dcd55d65342b055ea97a46ffff
The "physicial" screen orientation is incorrect. You can fix it in` the display settings by changing the orientation to "Portrait Right" but that will only work once post boot.
A better solution is to set the following kernel parameter video=DSI-1:panel_orientation=right_side_up.

Out of the box, the display supports 50hz.
I've succesfully managed to use 60hz and even 90hz on Windows but wasn't able to do so on Linux yet.
The resolution is 1920x1200 (16:10).
You'll need fractonal scaling, on GNOME if it's not enabled you can do so with
gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"
150% is recommended, specially for touch but it's usable at 125%.
- Software controlled
- 21 levels
- Brightness keyboard keys functional
There is a physical switch to trigger the tablet mode in order to lock the keyboard and touchpad.
However it's not currently working. On Windows it appears to use PNP0C60 / INT33D3.
It's not working on Linux but there is some support for it.

There is a MEMSIC MXC6655 accelerometer in the device for detecting screen orientation.
Since Linux 6.9.0 it is supported and you can read its value.
However auto rotation in GNOME doesn't work even though the iio-sensor-proxy is able to read the device orientation. That is because it needs the tablet switch to work to enable auto rotation.
You can use this extension meanwhile https://extensions.gnome.org/extension/5389/screen-rotate/
