Re: ATI Radeon VE/QY dual head and XFree86 4.3.0-81.EL

["Cheryl L. Southard" <cld astro caltech edu>]

Hi All,

I figured out how to get the dual monitor setup to work.  I was on
the right track with the "MonitorLayout" option, but I had it in the wrong
place.  It shouldn't be in the "ServerLayout" section.  Instead, it should
be in both of the "Device" sections, and it shouldn't be
LVDS which means "laptop screen".  Instead, it should be like this:
        Option "MonitorLayout" "TMDS, TMDS"

It's all explained in the documentation in /usr/X11R6/man/man4/radeon.4x.gz

I still don't know why it stopped working when I upgraded from
4.3.0-78.EL to 4.3.0-81.EL, though.
