Issues with NVIDIA base mosaic

Elv13 · 2014-06-07 21:15:49

Hello,

I am currently using Xinerama for my screens but the NVIDIA blob have more and more issues with this. Creating a wibox in Awesome now take 3 seconds instead of <1ms with 1 screen. I am wondering if I can enable mosaic or xrandr instead.

Xrandr somehow mostly work, but I cannot move window across screens, something I need and want.

I have tried base mosaic, but only 2 of the screen power on. I have 1 PCI-E GTX610 and one GTX630 (I don't play video games, so I don't care about GPU power that much).

1) Is it possible to use base mosaic with different GPU of the same generation? (it _is_ technically the same chip)
2) Can I have different resolution / DPI for each screen?
3) Is is possible to rotate screen in mosaic?
4) If 1,2 and 3 are possible, what's wrong with this command?

What I tried:

sudo nvidia-xconfig --base-mosaic --metamodes="GPU-0.DFP-0: 1920x1200+0+0, GPU-0.DFP-1: 1920x1200+1920+0, GPU-1.DFP-0: 1650x1050-3840+0, GPU-1.DFP-1: 1650x1050-5490+0"
