ubuntu 11.10 and dell system and monitor

I have a dell poweredge sc440 and a just gotten dell s2209wb 22" monitor. I had been using a viewsonic ve150m. The system works fine with the viewsonic, but the dell s220 gives a message of vga cable not connected to vga on system startup. However, when I start the system with the viewsonic and then connect the dell the display works.

Can anyone give me some advice?

Thanks

Maybe your VGA cable is bad.
Are you tying to double monitor?
Anyway, the Dell s2209wb has a DVI input. Does your computer?
DVI is better than VGA, in my opinion.
I connect a D600 to a HP w2207, and I use DVI, without a problem.
Does your keyboard have a fn+f8 style shortcut? Because it doesn't automatically detect it unless the system sends input.
