Just an update on my previous posts.
It is easy display manager as Delta Whiskey suggested, however it required running the installer in windows XP compatablity mode to get it to install otherwise the driver installation stage fails.
Don't think samsung makes x64 drivers for this laptop either
Another oddity is that the r505 spec on their site does not match that of the machine I have.
For instance the spec says HD3200 and AMD QL62 cpu yet the one I have has a RM72 and a HD3470

Not that i'm complaining
