I have a working, triple-monitor configuration running as a single X screen. (GeForce GT 640 + 3 Samsung SyncMaster 940BX.) When I maximize a window, it fullscreens to a single monitor only. This works great!
When I add a second, independent X screen (GeForce GT 720 + 1 Dell 2408WFP) to the ServerLayout, maximizing a window on the original screen spreads it across all three monitors. Obviously, I’d prefer the original behavior. (Note that I am not enabling Xinerama in the ServerLayout, as I want the two screens to be independent.)
I am running driver 352.09 on x86_64 with an Intel i7-3570K processor.
A key observation I’ve noted, is that in the original configuration, a verbose log reports the following:
(II) NVIDIA(0): Loading NVIDIA Xinerama information
Whereas, the new configuration does not report such a message. Somehow, adding the new X screen keeps the nvidia driver from loading the Xinerama information needed by my window manager and other programs.
My question: Is there a way to preserve the original behavior of maximizing to a single monitor while adding the additional X screen to the ServerLayout? And if it is not currently possible, is it a feature that could be added to upcoming nvidia driver releases?
I have tried many things, but am open to trying them again, or something new, per your instructions. These include:
- Adding Option "nvidiaXineramaInfo" "true" to the relevant device. The documentation states that this is "true" by default, but I thought perhaps manually specifying it would force it back on.
- Turning Xinerama on for the entire ServerLayout. While not what I want, I was able to move windows between the devices, but was still unable to maximize windows to only a single monitor on the original device.
- Loading other Linux distributions, desktops, and window managers. None of the ones I tried were able to maximize windows to a single monitor on the original device, when the second device was active.
I have attached the configuration files and verbose logs for the working, “One X Screen” configuration and the not-yet-fully-working, “Two X Screens” arrangement, and an nvidia-bug-report for the desired arrangement.
Thank you for any help you can provide!
