imx7dsabresd startx problem

[Ahmet_Cihan_AKINCA]

Hi. I have an imx7d-based board with a seven inch LCD panel and I prepared my linux system by using instructions of NXP documents.

fbset -fb /dev/fb0 -g 800 480 800 480 18 -t 33333 14 14 14 14 40 8

I can see the login screen. With

cat /dev/urandom > /dev/fb0

I see a noisy screen. But I can't start X system.

What should I do?

Thanks and best regards..

Here is my error log;

Thank you Bio_TICFSL. I prepared my linux by using yocto, it wasn't ubuntu. Let me try ubuntu now. I didn't like yocto anyway..

Best regards..
