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 gpu computing 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 to this:
Section “ServerLayout”
Identifier “layout”
Screen 0 “nvidia”
Inactive “intel”

nvidia-settings -a “[gpu:0]/GPUFanControlState=1” -a “[fan:0]/GPUTargetFanSpeed=50” gives me:
ERROR: Error assigning value 50 to attribute ‘GPUTargetFanSpeed’ (men:0[fan:0]) as specified in assignment ‘[fan:0]/GPUTargetFanSpeed=50’ (Unknown Error).
So i cant regulate fan speed of both 1080tis or overclock them. Any help?
thanks
