Hi, I don’t know if this is the right forum to come to, to ask for help. If not please direct me to where I should be asking, and my apologies for the disturbance. This might be an nVidia issue, but I am suspicious that it may have something to do with OpenSuSE 15.4 x86. I am running the KDE desktop with Plasma. I have two monitors that I want to be clones and show exactly the same display on both monitors. I have fiddled a LOT with the nVidia X Server Settings app but simply no joy getting this to work.
At this time I have the nVidia app configured, so that the X server display configuration is showing my two monitors, a Westinghouse and a Samsung monitor positioned on top of each (both at pos 0,0) and set with the same resolution of 1920 x 1080. What is happening is that the Samsung shows an extended portion of a desktop with the background image and desktop icons placed there. The Westinghouse shows a desktop with no background image and is where the kicker bar and all my window shells are showing up. The only thing that can interact with these two desktops is the mouse cursor. I can move the mouse cursor from one monitor’s desktop to the other monitors desktop, but nothing else.
The reason I am suspicious of OpenSuSE or perhaps KDE, is that in their Systems Settings → Display and Monitor → Display Configuration, ONLY the Westinghouse monitor is shown and is configurable. There is nothing shown for the Samsung monitor. So apparently nVidia’s X Server tool is capable of seeing both monitors and allowing each of them to be configured, the KDE Systems Settings tool cannot see the Samsung terminal. Seems wrong to me!
Here is my current version of my xorg.conf file with most of the comments removed to reduce the clutter.

Much appreciate and thanks up front for all your suggestions, I am stumped on this problem. I have fooled around with the Xinerama (causes system initialization/boot up to fail and drops into inet3 shell mode) and BaseMosaic (which I think is inappropriate for what I want) options also. Let me know what other information to acquire and I will gladly submit it.
