Hello, I am writing this mail to get some help for my problem I faced. I wrote a simple app which fills my HDMI monitor with red color. This app just opens /dev/fb0, which is the framebuffer driver file for HDMI display driver, gets screen information via ioctl, fills the color with mmaped buffer.
This application works well on debian-BBB Linux, which covers default desktop image with the red color. However, when I removed lightdm via apt-get remove command to disable the default GUI, this frame doesn’t work. To be specific, when I removed lightdm, it seems that the tilcdc driver couldn’t find my monitor. My monitor shows the message (“There is no device connected to the HDMI port”). Should I do something special to enable display when I remove the lightdm? It would be very appreciate if someone can give me some advices. Best regards. Heecheol, Yang.
