I have built core-image-sato for my device but device fails to boot into GUI mode.
When I looked at Xorg.0.log file, found that Xserver is unable to find device node(/dev/dri/card0).
This question is asked in multiple forums and people could resolve them also but none of the solution seem to work for me in my device running yocto warrior branch with 4.19.62-intel-pk-standard kernel.
I would be really tankful if you could help me to get Xserver working?
Attaching Xorg.0.log for reference,
