I have a pc with Ubuntu 18.04 with three monitors connected. Two monitors connected with VGA and HDMI to my graphics card (GeForce GT710) and one monitor connected directly to the motherboard (Asus H81M-K).

during boot, all three monitors show image but once ubuntu finishes booting only the monitors connected to the graphics card are recognized. I tried enabling the onboard graphics card in the bios and it still doesn't work.

this the xrandr output:

Screen 0: minimum 8 x 8, current 3840 x 1080, maximum 16384 x 16384 VGA-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 598mm x 336mm 1920x1080 60.00*+ 1680x1050 59.95

59.94 640x480 75.00 59.94 59.93

does anyone have any idea how i can get my third monitor to be recognized?

It is probably a driver issue. You will need to use the open source drivers because only one driver can be loaded at a time. It seems you are using the NVIDIA drivers which disable your Intel integrate GPU.
