When I run directfb sample df_sok, I got this error msg below, can anyone help? thanks.

I'm using imx6q board, and build from latest ltib without any problem.

root@freescale /$ df_dok

Did you try df_dok - - dfb:no-vt, if this doesn't work check the full debug trace

$> df_dok --dfb:debug

Also, you may need to compile the Linux Kernel with "Virtual terminal". You can find this option under Device Drivers ---> Character Devices ---> Virtual terminal.

Hope this helps
