[mdlug] Location of xorg.conf in Ubuntu 18.04

[R Kannan]

Hello,

I did some more digging and found the followig in /var/log/Xorg.0.log

[  3350.717] (II) NVIDIA(0): Setting mode "DVI-I-0: nvidia-auto-select 
@1280x1024 +0+56 {ViewPortIn=1280x1024, ViewPortOut=1280x1024+0+0}, 
HDMI-0: nvidia-auto-select @1920x1080 *+1920+0* {ViewPortIn=1920x1080, 
ViewPortOut=1920x1080+0+0}"

I am not sure where it is getting this offset of 1920 for HDMI port from 
as I have the following line in /etc/X11/xorg.conf file

    Option         "metamodes" "DVI-I-0: nvidia-auto-select +0+56, 
HDMI-0: nvidia-auto-select *+1280+0*"

Apparently it is ignoring /etc/X11/xorg.conf file for some reason. More 
digging is needed.

Thanks
