For this system , we are planning to use DUAL display with HDMI & LVDS.
we  see that that only HDMI is working and LVDS screen is blank.
However, we notice that XRANDR is is showing LVDS as connected

use semothing like this

xrandr --output LVDS --right-of HDMI --auto

Yes, i did try the option that you have mentioned : "xrandr --output LVDS-0 --right-of DVI-0 --auto " . There was no exception or error during execution and LVDS SCREEN was blank.

Again tried the same experiment with VGA and LVDS connected. During this trial "xrandr --output LVDS-0 --right-of VGA-0 --auto" LVDS worked as expected.
Confused.


BTW you guys are amazing. Pasted all that stuff but did you also find time
to read the man pages? Or at least execute xrandr --help

usage: xrandr [options]
   where options are:
   --display <display> or -d <display>
   --help
   -o <normal,inverted,left,right,0,1,2,3>
