Hi Thierry, >From memory I did set "on demand" mode and it worked correctly.
Now it is a strange situation, kernel 5.4.0-28 is the latest that boots correctly in my setup if only built in screen (on later versions, it hangs shortly after Linux boot started, Lenovo sign still there and progress circle not shown anymore) Latest kernels boots correctly if there is external screen plugged by HDMI (so, maybe "hung" from 1st case it is just that still somehow expects external screen...)
