CentOS - Jun 2007 - Install XGL under CentOS 5 with ATI X600 and dual-head configuration

Hi again.

I've got a laptop with an ATI X600 inside, perfectly working xorg with
dual head configuration, 2 desktops (without xinerama).
I've got 2 xorg.conf files, one for propietary ATI (fglrx) driver, and
other to use the open source driver. The difference is very notorious.
The problem I have is that I read (Saint Google) that to work with
compiz/beryl and dual-head configuration, I need to install XGL. That is
why I wrote this message.
Has anyone been installed XGL under Centos 6 using dual-head configuration
and fglrx driver?

Does anyone know links to tutorials/repositoris that I can use to install
XGL?

Does anyone know information on How-to configure XGL to allow the
dual-head configuration use?

My system is updated and is working perfectly with xorg. But I want to
know how to run beryl in my system and make a mini how-to to configure it
with xgl+fglrx+dual-head and send it to centos wiki. I have been reading
info about the same, but under Ubuntu or FC distros, but it is incomplete
or difficult to translate on Centos distro (at least for me).

Thanks you for any start point (links, howtos, repositories, etc...) that
help me in this documentation/configuration process.

Regards

Hola de nuevo, colisteros.
Tengo un port?til con una ATI X600 en el cu?l tengo perfectamente
configurado las Xorg para el uso de 2 monitores con escritorios
independientes, sin Xinerama.
Tengo 2 xorg.conf, uno para usar el driver propietario ATI (fglrx) y otro
para el uso del driver de c?digo abierto y, sinceramente, se nota mucho la
diferencia entre el uso de uno y otro.
El tema es que para que beryl/compiz funcione con el driver propietario de
ATI y con 2 monitores, se ve que necesito hacerlo usando XGL. Por ello es
por lo que os escribo el siguiente e-mail.

?Alguno ha instalado XGL bajo CentOS 5 usando fglrx y 2 monitores?

?Alguno conoce links hacia tutoriales/repositorios que pueda usar para
instalar XGL?

?Informaci?n sobre c?mo configurar XGL para usar 2 monitores?

Indicaros que el sistema est? actualizado y est? funcionando perfectamente
con las xorg. El tema es que me apetece probar c?mo montar beryl en el
mismo y hacer un peque?o HOW-TO para 2 monitores y publicarlo o mandarlo
al wiki, ya que he visto informaci?n para Ubuntu/FC6, pero o es incompleta
o dif?cil de adaptar (al menos para m?) a Centos 5.

Os agradecer?a mucho cualquier punto de partida que me ayude a
documentarme sobre XGL y configurarlo bien para su uso con 2 monitores, ya
luego ver? c?mo meter compiz o beryl.

Salu2

Well, some progress.

I had installed xgl and appears to be working.

Now the problem is that on the right screen don't load the desktop, I can
only view a black screen and the mouse cursor appears as a "X" over
that
screen.

I can play with beryl on the laptop flat fine (1600x1050 with 24bpp), but
not with the external LCD (1280x1024 with 24bpp). The right screen
(external LCD) works fine witout XGL, and appears to work fine with Xgl,
but the secondary desktop is not loaded into the secondary screen.

With "ps aux" I can see 2 xorg process and only one Xgl process.

Perhaps I need to make modifications into any gdm configuration files?
What files I have to modify? How?

Perhaps I need to make modifications into xorg.conf to adapt it for Xgl use?

Please, I need help about this.

I attach the relevant .conf files to the e-mail.

Regards

I'm actually curious about how you got the XGL part installed (I've been
trying to get CentOS 5 + fglrx + XGL + beryl + dualhead as well).
I got everything but XGL and beryl working.

As for the dualhead part.
You want to not use XINERAMA or TwinView (nvidia specific) but instead use 
Pairmodes (ati specific).
It basically amounts to having only 1 device and screen section (ie. 
you configure everything for one single screen) and then you add to the 
main Device section

Option "Mode2" "1920x1200,1600x1200"  (second monitor modes)
Option "PairModes" "1440x900+1920x1200,1440x900+1600x1200"

Once X is booted you can use xrandr (command line) to switch between 
various display modes (and aticonfig --lsp, aticonfig --set-powerstate=X, 
aticonfig --query-monitor also come in handy).

Here's my /etc/X11/xorg.conf (this is for an ATI fglrx driven 1440x900 
LCD with occasional external monitor/LCD/projector):

         Identifier     "Layout"

Thanks,
