When enabling xinerama on a 2 monitors config, the call to nvFBCGetStatus() gives a struct of type NVFBC_GET_STATUS_PARAMS with members dwOutputNum = 0
My later call to nvFBCCreateCaptureSession() will fail.
Is it possible to use NVFBC while Xinerama is enabled?
In looking for an alternative to Xinerama, I’ve found that XRandR would be an option, but here: https://wiki.archlinux.org/index.php/Multihead#Xinerama
I’ve read that
Since randr version 1.5, it has been possible to combine monitors into one virtual display. This is an updated version of what was possible with Xinerama and works with open source drivers and does not require an Xorg restart.
For an image processing reason, I’ll need CUDA (version > 6.5) to be available.
I’ve also read that TwinView would make it for 2 monitors. But in a short future I would have 4 monitors instead of 2, which makes TwinView not usable.
