Hi Paul,

There were two things I had to do differently.

To kill my X session I did

ps aux | grep xdg

Then I killed the xdg process.

Step 4 says to find the string "ConnectedMonitor" in xlog.txt.  I couldn't
find that in my xlog.txt.

A manual look at that file found this line.

(--) NVIDIA(0):     MARANTZ JAPAN, INC. marantz-AVR (DFP-1) (boot,
connected)

I took note of that when I updated my xorg.conf.

        Option  "ConnectedMonitor" "DFP-1"
        Option  "CustomEDID" "DFP-1:/etc/X11/edid.bin"
        Option  "IgnoreEDID" "false"
        Option  "UseEDID" "true"

David
