I do not want to use t= he iGPU HD4600, also it could save energy/battery lifetime, but there is no method = to switch between both. I'd like to use this GPU, not the slower HD4600 Haswell iGPU. As far as I know from other notebooks I ran with FreeBSD, this x11-drivers/xf86-video-scfb as well as its VESA counterpart is insanely slo= w and not very usefull for high resolution displays. It might be useful having a display a= nyway. But, anyway thanks for your assistance, very appreciated.
