Hi Sanjay,
Most useful would be the pertinent part of your kernel log
(dmesg | grep -A 10 -B 10 drm) as well as some of the content
of the following sysfs files (edid is binary):
/sys/class/drm/card0/card0-*/{dpms,edid,enabled,modes,status}
Eventually also:
grep /sys/module/i915/parameters/*
and
uname -a
