Hello,
I was having trouble getting my new 1600x1200 LCD to work on the DVI port
of a Radeon VE QY with XFree86 4.2.99.2. I tracked down the problem to
RADEONDDCModes() in radeon_driver.c. The first loop contains a break
statement which causes it to process at most one DDC detailed timing mode.
Removing the break as in the attached patch fixed my difficulties. I
include the DDC output information for reference.
Cheers,
Wayne
