dual screen problems

[Per Arne Nilssen]

Hi,

I have several Dell Latitude D505 with Intel 855GME chipset.

I have a question regarding setting up external monitor.

Ubuntu Breezy with all updates finds my beamer perfectly. I can toggle
between laptop screen alone, laptop and beamer and just beamer.
When using laptop and beamer mode I do get a terrible output from my
beamer.

Does anyone here know about this issue, and how I can fix it?

Thanks
