Acer Aspire E17 with Nvidia Optimus


Can somebody show me a right method how can I setup my Nvidia Optimus “supported” Acer Aspire E17 E5-773G-52PB to use minimum the Nvidia card?
Sorry, when I bought this notebook I doesn’t from the two different video card (even two differnt manufacturer) are inside. On the machine and in advertisements of the shop where I bought everywhere was mention only one card.Sorry so far I couldn’t found from this notebook a full and correct specification nowhere anything.

As far as I know, the Optimus systems do not have discrete (dedicated) Nvidia graphics, just an Nvidia GPU that uses the video memory of the Intel GPU. So I can use the Intel GPU alone for power savings, or Intel + Nvidia GPU together for the faster rendering if the software supports it, but not Nvidia alone. But I’m not sure in this! For me the power saving is not important! I would like to use only the notebook’s monitor.

I would like to use the two card together or the NVIDIA card alone.Sorry, I cannot switch off either GPU off in the laptop’s BIOS. I’m meaning on a BIOS update (maybe in an updated BIOS I will can switch off either GPU), but I need for the legacy BIOS option also in the future (I’m using some live and other not windows distros).A disease of the Acer that the legacy BIOS option missing from the new BIOS versions (they makes only windows notebooks).
Maybe if somebody can offer me an other solution to switch off either GPU please write it down.
Now I can du it with this script:

% fetch
% make -C /usr/ports/sysutils/acpi_call install clean
% vim # read it before executing!
% sh # as root user

I already tried a lot of different method from the network so far without any luck.I need an not port collection method.

Last time I tried these: this is a little bit “rough” :-)

but I couldn’t found nowhere “nvidia-driver-optimus”.

My system use BSD boot loader not GRUB.

I’m using legacy BIOS mode.
