Compiz Fusion + Dual Head + Xinerama

When I try to run fusion-icon with two monitors connected, I get this error:

compiz (core) - Fatal: No composite extension

Is there an extra module I need to load in xorg.conf for xinerama + compiz?

thanks in advance

Re: Compiz Fusion + Dual Head + Xinerama

as far as i know you cant run compiz with xinerama but just to make sure you do have

Section "Extensions"
    Option         "Composite" "enable"
EndSection

in your xorg.conf right?

Yea, you're right.  You need to use mergedFB with to get compiz working with ATI on dual head.  However, mergedfb requires you to use the open source drivers, thus making it not  compatible with my old (x300) card.

(in case someone is reading this later on, the list of supported cards with the (open source) radeon driver is here: http://www.botchco.com/alex/radeon/merg … eon.4.html)
