I am trying to redirect the Qt output to /dev/fb2 which is mapped to LVDS display. I am not able to do.Primary display is /dev/fb0 which is mapped to HDMI display. I am using freescale IMX6 saberautoboard.I have tried using the following command 

./qtapp -qws -display Linux:/dev/fb2. But I am getting following error. 
Linux: driver not found Aborted

Please help me regarding this.
