We’re using the “Capacitive Multi-Touch Display” with the Hannstar 10.1" LVDS display. Our application must be rotated by 180 degree.
I’ve tryied the following:
root@colibri-imx7:~# xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1280 x 800, current 1280 x 800, maximum 1280 x 800

I am using Apalis Evaluation Board with Apalis i.MX6Q SOM board system. Software version: Apalis-iMX6_LXDE-Image 2.8b6.184 20190401. I tried the below two options to rotate the display,
[OPTION1]
I tried to edit the file “/etc/X11/xorg.conf” to include the parameter “Option “Rotate” “UD””. after the change, the system cannot display but can boot up properly.
[OPTION2]
when i use the command:
xrandr --output “DISP3 BG - DI1” --rotate right
The display look a bit abnormal and no background at first. i need to move the mouse around and let the display to display it background.
The above 2 methods have the problem to rotate the display properly, Do you have a third option to rotate the display?
