integrated graphic card as primary monitor + nvidia gtx 1080ti for hashcat - hashcatnoobiii - 09-11-2018
hi folks, im having some trouble on configuring nvidia-settings in xorg. i have i7 8700k and 2x gtx 1080tis.
i would like to use integrated graphic card of i7 8700k as primary monitor where i can read and do my research stuff, 2 1080ti should only do gpu computing. Ubuntu 16.04 is the os, nvidia 390 driver is insalled. in bios integrated graphic card is enabled (igpu) , everything works fine. i have primary monitor and 2x 1080ti do hashcat on 100%, accept i cant set --cool-bits=28 in nvidia-settings which lets me overclocking and fan speed regulation of both cards. my xorg.conf gets overwritten after every boot to this:
