How to set DSI panel to landscape mode for TX2

Hi all,
The display is by default in portrait mode, we need to rotate it to the landscape mode.
I use the “panel-s-wuxga-8-0” as the default panel, Jepack version 3.1.
I disable the default Ubuntu desktop, and run my own Qt5 application.
I set the “nvidia,out-rotation” to be 90 in “panel-s-wuxga-8-0.dtsi”,it’not working.
Then i set the “initial_rotation” to be 1 in “fbcon.c”, it seem only the lcd console is landscape mode, my Qt App still portrait mode.

I sincerely appreciate anyone help me.


I believe Xorg does not know your monitor has rotated. Could you try to use xrandr to rotate the monitor 90/270 degree and run Qt App again?

Thank you,I did some modification in Qt open sources, then lcd panel can be landscape.
