Sorry Chris, I spoke too soon. The working config was single screen/monitor config, as attached here. Commenting of SNA line made it work. The dual screen configuration is still failing as before. And if I comment out the SNA lines I get this in the X log. [3056612.622] Requested Entity already in use! [3056612.622] (EE) Screen 1 deleted because of no matching config section.
