Ubuntu 11.10 Dell vostrum Intel® Sandybridge Mobile x86/MMX/SSE2

Displays ... correctly detects and identifies Viewsonic 27" VGA monitor, but monitor says it's receiving no signal

Plugged into another monitor (Sony 20"), same result.

$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

I've browsed these forums and tried everything that I can but nothing has worked. I need a stepwise troubleshooting plan.
