I would like to pose I hope a simple question. If you desire something 
different than the default computed from the EDID data, what can you do. 
Unix variants have always had a configuration file with preferences that 
allow one to override the default. I think you said you made your own 
EDID. Where did you put it so the system pays attention. When the Gnome 
display manager configures the monitor, where does it put that data? 
Where in the process is the EDID read. I do not use Gnome and am looking 
for a way to get back to the flexibility xorg.conf provided. When I 
tried to run X -configure it referred me to "Please consult the Fedora 
Project support at http://wiki.x.org" web page that described the old 
xorg.conf setups. Fedora is becoming too opaque to be useful:-(
