Dual Head + radeon driver + mergefb + beryl. DRI problem now.

[ArcosCom Linux User]

Well, as my "fglrx+xgl" message don't appear to be interesting, I tried to
configure my system using radeon with mergefb (thanks to google for it).

I have readed that to use DRI with 2 monitors and radeon driver, I need to
say X I only have one and configure the "device" and screen sections as
these:

Section "Module"
	Load  "bitmap"
	Load  "dbe"
	Load  "ddc"
	Load  "fbdevhw"

EndSection

EndSection

		Virtual 2960 1024
	EndSubSection
EndSection

Before that, the Xorg.0.log file, say to me that I test with MergedFB
option (I had 2 devices + 2 screens sections and working fine, but without
DRI).

Now, Xorg appears to load DRI, but disable it and I don't know why.

I can see this in my Xorg.0.log file:

Take care into the line:

Does anyone want to help me?

Thanks!!
