Understanding of Composition call flow in XServer

[uday kiran pichika]

Thanks Michel. Yes, it is loading Intel video driver. To confirm this, i
had enabled logs in Intel video Driver (SNA), logs are floated into
xorg.n.log file(when started X using startx) .

I have a question on capturing the logs when system rebooted. Can you
please help where to enable this ?
