I am new to DirectFB and running DirectFB sample program on linux device. Compiled Using arm-cortexa9-linux-gnueabi-g++ compiler.

While executing getting below error

fbset -i output is

Content of /etc/directfbrc

no-vt

Looks like problem is in first two lines of sample program itself
DFBCHECK(DirectFBInit (&argc, &argv));
DFBCHECK(DirectFBCreate (&dfb));

Am I missing anything in basic setup of directfb?
