Re: XFree86-4.0.3-6 & 2nd Monitor

[Hugh Caley <Hugh_Caley affymetrix com>]

I'm having a similar problem on a Dell 640 using XFree86 4.3.0 and a 
Radeon Mobility 7500.  The primary display is always "cloned" to the 
secondary, even with a second screen set up for the secondary in 
XF86Config, and Xinerama on, etc.  I can freely move my cursor between 
the two screens, and drag an app from one screen to the other, but 
screen two always mirrors one and they interfere with each other.

According to "man radeon", the "CloneDisplay" setting is only used when 
there is only one screen in the config file.  "CloneMode" says if you 
don't have this line while clone is on, the modes specified for the 
primary head will be used for the secondary head.  This would seem to 
indicate that neither of these options are useable if there is a second 
"screen" section in XF86Config (which I have), and sure enough the 
options don't seem to make a difference, and yet the display is cloned.  
Somethings wrong here.
