***** If anybody has trouble with her/his backlight turning off after a while: This happens only if the "Framebuffer Console support" is enabled. This framework calls to switch off the backlight after some time of inactivity. And this happens if the console shares the framebuffer with a graphical application. That is why in the kernel in my board support package the "Framebuffer Console support" is disabled. In this case the framebuffer is owned only by the graphical application. **** In my previous Qt work I had Framebuffer Console support enabled. Was that incorrect? The last sentence in the above sounds like I didn't need to enable Framebuffer Console support. Does Qt application = graphical application?
