I have an ASUS G74s laptop with an NVIDIA 560M card, running Fedora 17:
Linux localhost.localdomain 3.4.3-1.fc17.x86_64 #1 SMP Mon Jun 18 19:53:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
I am using the NVIDIA configuration tool and have a dual monitor setup.
The first monitor, "A." is my laptop monitor. The second monitor, "B," is a 17-inch Dell LCD screen I borrowed from a desktop. Everything *almost* works perfectly. I set the monitors up in "Twinview" mode with the Dell screen to the right.
My only problem is this. I would like to keep my "regular" desktop on screen "A" -- the desktop wth my icons, panels, etc. However, when I add the new screen, my regular desktop comes up on screen "B". It doesn't matter which one I choose as my "Primary" screen. Basically, I end up hitting "apply" and "cancel" five or six times and eventually it comes up the way I want. While it happens eventually, I never know which time it will work. It doesn't matter which one I make "primary," I've tried it both ways, and I've switched it when I go through the cancel/apply ritual. Once it's set up, everything works fine.
Is there some configuration choice I'm missing? How can I tell the driver that I want my "original" desktop on screen "A", and the (empty) new desktop on "B"?
