Hello,
I solved my Nvidia Optimus problem but I now face another issue.
A bit of background for future readers. I solved the Optimus problem which seems to have 2 solutions at this point. 1 solution is bumblebee + screenclone + optirun. However, this only works with 1 external monitor (i.e. laptop monitor + one external monitor). To get 3 monitors to work (laptop + 2 external) I had to use /etc/X11/xorg.conf and manually set it up. As far as I know, you cannot get 3 monitors with bumblebee + screenclone + optirum/primusrun.
Anyway, the current solution works great. However, I have Xinerama on in my xorg.conf file (in /etc/X11). This means RANDR is not loaded and I cannot (for example) run 'nvidia-settings'. Also, even though I can't notice any poor performance, tools such as glxspheres64 report very low throughput (about 15 times lower than normal).
I removed the "Xinerama" 'on' option from xorg.conf and I can now launch nvidia-settings. However, I now have 3 screens and I cannot transfer windows across them. What's the point of having 3 screens if windows are bound to one of them? Performance also seems to be much better (again, I can only tell by numbers from the benchmark tools).
Is there a way to have xinerama disabled but be able to move windows between screens?

Have you looked at offloading with RandR?
