I finally manages to install Ubuntu on Myria MY8307. I have two big issues, probably related.
To have the screen in the right orientation for landscape use with the keyboard, I need to apply xrandr -o right. Afterward, the screen display the current orientation but the pointer is rotated 180 degrees along with the system of coordinates. If want to click something from upper left corner, I need to click on the lower right corner for example. I tried using this script and setting a different Coordinate Transformation Matrix, but none of these helped me.
I installed the following driver for my touchscreen. The cursor moves reversed on Y, the whole screen moves the cursor in 1/4 out of height and width. While dragging my screen making selection, I can see my selection in the top left corner, while the mouse pointer actually moving in the bottom right corner.
Any ideas on how to fix my issues? I would also like to note that I tried to use iio-sensor-proxy and then to remove it but that didn't change anything.
