Need help with monitor resolution Dell Optiplex GX620

[David Trask]

Ok folks...another one...

I have a bunch of Dell Optiplex GX620's that I want to use in my lab. 
They have one video output with a DVI-VGA dongle.  I am using a DVI to VGA
adapter to connect to my VGA only ACER G185H monitor which has a native
resolution of 1366x768 running at 60 hz

So...no matter what I try (I've pasted my entry in lts.conf below...and
I've tried varying options within by commenting things out...etc)  My
xrandr -q output on the thin-client says that VGA1 is active and for modes
up to 1024x768 (which looks silly on a 16.9 monitor of this size)  It also
says DVI1 is disconnected.  I'm running Edubuntu 12.04....and I'd really
like to solve this...it's about the only thing I have left.  Any ideas?

  [00:12:3f:c0:a8:81]
  HOSTNAME = L11
  XRANDR_DISABLE=True
  XRANDR_OUTPUT_0 = "VGA1"
  XRANDR_OUTPUT_1 = "DVI1 --off"
  X_MODE_0=1366x768
  XRANDR_RATE_0 = 60
