I tried to use two NVIDIA cards for lot monitors, but I got error.
Cards are Quadro2000 and GeForce GTX750Ti. Use nvidia driver on Linux 4.6.2-1 x86_64.
Distribution is Manjaro Linux stable latest.
I was going to use Base Mosaic, but I understood they don’t support NVIDIA Mosaic.
I use Xinerama with three screens now. It’s very unstable but work.
But I got same error when enabled Base Mosaic or MultiGPU.
