Before I plunge into the details, does anyone have a working xorg.conf
for such a setup? I would prefer to start with something that works
rather than describe in detail something that doesn't work.
Maybe just dump the xorg.conf? If you use a desktop environment then it
likely has a GUI tool to set the monitors up. Or use xrandr?
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.
