      Is there a way to enable sleep for built in LCD to
      turn it off to conserve power and turn on/wake up by touch?

      I’m using Debian image.

      Thanks

          @mgrouch You need to create a program for that

          I do not see how. There are examples for displaying things on ILI9342C
          using framebuffer and LVGL.
          I do not see how to turn off backlight on ILI9342C. Is there some code example? Or command line utility with the code to control brightness? I was able to code that on m5stack tough on esp32 which has same ILI9342C.

          Also how to wake up screen by touch?
          I guess with brightness off touch functions are still there. So I need example of code listening for touch event and controlling backlight (voltage of it?) on ILI9342C.

          I need some help.
          Thanks
