Hello,
I've been running Kubuntu for about 3 years now... starting on 10.04 Lucid Lynx. Ever since upgrading to 12.04 earlier this year I seem to be having sporadic issues where my dual monitor setup (controlled by Nvidia Twinview) randomly merges the two monitors and puts the exact same screen on both monitors. My personal setup is as follows:
- Dell Latitude D820 (15.4" monitor) on docking station, and this is used as monitor 1... on the left and using a 1280x800 resolution.
- Dell E198WFP 19" LCD monitor used as monitor 2... on the right and using a 1440x900 resolution.
When this occurs, it seems to preserve the dual monitor configuration but presents the same exact image on both monitors. By this I mean that when I move to the right of monitor 1, the mouse does not get to monintor 2... it simply drags the 1440x900 section of monitor 2 over to monitor 1 (and I see this same image on both monitors).
There never seems to be a specific event that will make this occur. Sometimes my machine will run for several days without it happening while sometimes the problem may occur several times in a single day. The only fix I have ever been able to find for this is by logging out of my session and basically restarting X. Any help/guidance on possible solutions for this would be great.
Below is the current configuration of my Xorg.Conf if that helps anyone.

If desired, I can send pictures showing what a good vs bad session looks like on my monitors, and I can also provide screenshots of a good vs bad nvidia twinview settings window.
