Comment 15 for bug 27667

Yeah, the goal is that X can do this by itself, and I guess other
distros are using "get-edid|parse-edid" or something similar to make
this happen. Since your get-edid output is similar to the one I get on
my samsung syncmaster 900NF monitor, I guess that X discards your
monitors edid information too. Are you sure you don't have the monitor
section filled with data about the monitor when using the "nv" driver?
I guess that nvidia binary driver could have separate edid code, but I
doubt that "nv" has one.

I hope we'll have some code in Xorg server soon, so you'll be able to
test the fix.
