I attach a report from inxi -Gay showing incorrect DP-0 monitor resolution plus 
my xorg.conf and parts of Xorg.0.conf

When I move to run level 5 in a fresh system start, the result is not always the 
same.  Sometimes DP-0 (on the right) is receiving signal for a short time. 
After 15-30 minutes DP-2 (on the left) goes dark and I have to reboot. Sometimes 
one or the other monitor will change to 900x1600 on its own without any user 
action.

Roger
