Tried it, doesn't work. I get the resolution for my local system which
has a dual head setup like is shown. The remote system is a single
monitor setup so I'm pretty sure I'm not getting the resolution of the
remote system.

Did you try xdpyinfo?
'man X' gives you an intro to the available X commands.

I'm searching for a command line utility of some fashion to let me
get the Xwindows screen resolution from a remote system. What I'd
like is very simply a command, utility, log entry that I can reliably
tell that "System X, over there on the network, is running an
Xwindows session at 1920x1080."
Does anyone have any ideas on how I can accomplish this? So far
xrandr doesn't seem to let me do it. There's lots of "Setting mode"
entries in /var/log/Xorg.0.log but no easy way to tell if that's the
actual resolution currently running.
