Naviathan, thanks again for the input.
After having spent a number of hours with the Separate X configuration, I have resolved that, there are problems with that option and my system. Unity-3d will not work in that environment. Also, as I mentioned the Ubuntu's system settings also fails with the RANDR error message.
I changed nvida drivers. That didn't help. I added the line, "UNITY_FORCE_START=1" to the /etc/environment configuration. This gave me no Unity-2d or Unity-3d. I had to cntrl-alt-F1 to get to a terminal window to remove the configuration and reboot to make the system usable.
I went back to the Twin View configuration which takes fuller advantage of my video adapter and allows the functionality of Unity-3D. I'll revisit Separate X if someone has some information that make make it work.
I have resolved to make a workaround that I can live with in the meantime. I changed the compiz settings to (Unity Plugin/Experimental):
Code:
Launcher Monitors: Primary Desktop
This seems to have removed the stickiness between the Monitors.
After having been plagued with the problem for over a year I'm surprised that I haven't seen this fix in any of the suggestions. I had been using the popular suggestion to lower "Edge Stop Velocity". However, the problem with that was that by the time the value was low enough to resolve the issue, you had to fight to get the menu on the left monitor.
Anyway, I hope the developers work out the problem with not recognizing the dual monitors under the Twin View option.
