Ok.
But I probably have a lot of things to learn on this. I hope to learn as fast
as possible. Now, although bumblebee works with nouveau and virtualGL, see,
$ optirun -c yuv glxspheres64
Polygons in scene: 62464 (61 spheres * 1024 polys/spheres)
Visual ID of window: 0x20
Context is Direct
OpenGL Renderer: Gallium 0.4 on NVD9
90.895740 frames/sec - 78.672081 Mpixels/sec
92.517988 frames/sec - 80.076169 Mpixels/sec
The command xrandr returns,
$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x47 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs:
3 outputs: 5 associated providers: 0 name:Intel
As if I had just one video card.
Finally, it is found in other forums that,
1-Nvidia's optimus provides the best performance but does not allow for gpu
switching and powersavings;
2-PRIME for nouveau provides GPU switching but with a lower performance; and
3-Bumblebee allows for GPU switching and power savings.
I need to use GPU's not only for graphical applications as in games but also to
run applications that perform mathematical computations without any graphical
deliver.
