I have a HP Zbook 15 containing both an Intel internal graphics card connected to VGA and the laptop screen and a Nvidia card, connected to two displayports.
I run bumblebee and intel-virtual-output to use a displayport of my laptop. And its working, stricktly speaking. I have two main issues:
1. On the monitor connected to the displayport, the mouse is slightly lagging. I tried to fix this by changing the file /etc/bumblebee/bumblebee.conf:
from
VGLTransport=proxyto
VGLTransport=rgb
VGL_READBACK=pboBut this did not change anything.
2. The second Xorg server, the one powering the displayport always consumes 20%-25% CPU. This slight hogging prevents my cpu from really dropping its speed and thus causes more heat and power consumption.
I am afraid at this point that this is a feature of my setup, but maybe you guys know how to fix this.

Hi, I have the same problem with CPU usage (40-50%) by the second Xorg server on Dell E6530.
