You can also try
Option "IgnoreEDID" "true" to your xorg.conf
file.
Section "Device"
Identifier "Videocard0"
Driver "radeon"
Option "IgnoreEDID" "true"
EndSection
I have to use this with my KMS switch that has the wrong EDID value
for
my older 19" CRT. The availability of this option may be driver dependent.
ATM, I'm working with Intel. According to Xorg.0.log, the Intel driver is
"not using" Options: IgnoreEDID, EDID, NoDDC, NoRandr & Preferred Mode,
apparently insisting I must use the horribly anachronistic 1024x768 on a
display capable of 4 times that resolution.
