Thanks, will try it tonight. BTW I just read this-

http://www.thinkwiki.org/wiki/Additional_options_for_the_radeon_driver

"...seems that Xorg incorectly discovers the external displays when
connected to a docking station/port replicator - the only solution to
this problem (at least that I know of) is to start the laptop (and
boot all the way into X) prior to inserting it in the dock...."

I had forgoten to add that I was connecting through a docking station.
Is there a known bug on such setups like its mentioned here? That's
the same behaviour my laptop+docking station is showing.

Thanks,
