XFCE4 + AIGLX + Compiz/Beryl [no windows decorator]

Question

Hi,
I'm a newbie in archlinux and xfce, so probably this is a newbish question.
I run AIGLX over a ati with radeon opensource drivers in xfce4.
It runs well , I activated composite on xfce and see semi-transparents panel and so on.
Today I'm trying to install and run compiz or beryl but without success.
I installed compiz-core, beryl-core, emerald, something else.
try to run compiz with replace but no windows borders appear (even if when I try Alt+Tab there is the typical compiz effect ).
So I decided to switch beryl... Try to run beryl-manager and change in beryl or compiz but without success.
I don't see windows border s:\.
I checked the default depth is 24, i tried to put:
beryl-manager &
emerald & 
startxfce4
in .xinitrc but the windows decorator doesn't appear.
Any idea?
Thanks in advice for the replys.

Answer 1

Okay I solved it.
This is a simple mini guide to installa compiz on xfce4 with ati open source drivers:
1) install ati open source drivers (look the wiki)
2) in xorg.conf (I have a ati radeon 9000pro):
Section "ServerLayout"
        Option         "AIGLX" "true"
EndSection
Section "Device"
        Identifier "ATI"                     # your alias
    Driver "radeon"
    Option "XAANoOffscreenPixmaps" "true" #needed for aiglx
        Option "AGPMode" "4"
        Option "DRI"     "true"
        #Option "EnablePageFlip" "on"
        #Option "AGPFastWrite" "yes"
EndSection
Section "DRI"
        Group        0 #"video"
    Mode 0666
EndSection
Section "Extensions"
       Option      "Composite"   "Enable"
EndSection
3) in order to run compiz you must NOT enable the compositor options in Window Manager Tweaks.
4) Install compiz-git for example using (pacman.conf):
[compiz-fusion]
Server = http://arch.nesl247.org/compiz-fusion/i686
4.1) install fusion-icon #simple systray icon .
5) Open terminal and run fusion-icon. Change (Select Window Manager) to compiz.
6) Enjoy your archlinux-box .
Buon divertimento!
