I can confirm there's a problem when attempting to use the Dual Head on the Intel 945 Express. This presents a significant visual miscalculation to users of netbooks and many entry-level laptops.

Without looking at any logs - it appears that the values that define each monitor are being mixed, and consequently, the visual output can be unusable. For example, the output on desktop display is scaled to the width of the 2nd vdu and scaled to the height of the 1st vdu, and finally clipped/cropped (not rescaled) to the resolution of the 1st vdu. In other words its a mess.

No Dual Head features are provided in the display settings and the reported resolution matches the clipping but not the rendering. Did that make sense?

Please test with hrev53787 or later, there have been many fixes to the driver which should help with this.
